Elke: understand the range before choosing
Elke develops automotive air-conditioning service chemicals and equipment. The current AutoMotoPart range is a focused group of twelve service consumables: PAG 46 and PAG 100 lubricants, a PAO 68 lubricant, oil and dye combinations, universal PAG oil, UV contrast dye, flushing agent and leak-stop products identified for R134a, R1234yf or both. These are professional-system products, not general oils or cooling additives.
AutoMotoPart currently lists 12 Elke items. The largest Elke groups are 12 air-conditioning service products. Elke totals can change, so a category count is orientation rather than proof that a particular reference suits a vehicle, workplace or job. The exact Elke listing, its current technical information and the item in front of you must agree.
What the Elke page actually covers
| Product group in this range | Current entries | Selection focus |
|---|---|---|
| Air-conditioning service products | 12 | Match refrigerant, compressor drive/type, exact lubricant family and viscosity, dye or sealer dose, service equipment compatibility and vehicle procedure. |
The twelve listed Elke entries are all air-conditioning service products. Eight titles refer to R134a and five to R1234yf, with several supporting both refrigerants. Four titles contain PAG 46, while PAG 100, PAO 68, universal PAG, UV dye, flushing agent and three leak-related formats add distinct choices. Overlapping refrigerant wording does not make their lubricant chemistry or purpose interchangeable.
Build a reliable shortlist
Record the vehicle, refrigerant label, compressor reference, compressor drive type and current service history before choosing a consumable. If the system has been charged with an unknown gas or lubricant, identify contamination rather than masking it with additional oil, dye or sealer.
| Check | Why it matters | Useful evidence |
|---|---|---|
| Refrigerant | R134a and R1234yf require dedicated identification, couplers and service procedures | Under-bonnet label, identifier result and exact Elke title |
| Compressor | Belt-driven and high-voltage electric compressors can require different electrical and lubricant properties | Vehicle and compressor-maker lubricant code |
| Oil specification | PAG 46, PAG 100, PAO 68 and other families are not viscosity synonyms | Chemistry, ISO grade, part reference and approved quantity |
| Existing contents | Unknown oil, dye, sealer, moisture or mixed refrigerant changes the repair plan | Recovery analysis and documented service history |
| Operation | Top-up, component replacement, leak tracing and flushing have different quantities and equipment | Repair procedure and measured recovered oil |
| Equipment | Injectors, hoses and recovery machines can be contaminated by incompatible chemicals | Service-machine, adapter and leak-sealer policy |
Do not select by the service-port connector alone. Confirm the system label and identify the recovered refrigerant, because adapters can be fitted incorrectly and vehicles may have been mis-serviced. If the lubricant specification cannot be established, pause the repair rather than choosing the closest viscosity or a product called universal.
PAG 46, PAG 100 and universal PAG
The present range includes R134a PAG 46 in two container sizes, PAG 46 with dye, R134a PAG 100 and an R1234yf PAG 46. Elke's official lubricant guidance lists PAG grades separately, including ISO 46 and ISO 100, because the compressor requirement determines viscosity. Container size and refrigerant compatibility do not change that requirement. Keep opened PAG tightly sealed because moisture uptake can compromise an A/C system.
The title Universal PAG Oil indicates broader intended coverage, but it is not evidence that every compressor, refrigerant or electric-drive design accepts it. Compare the full Elke technical data with the vehicle or compressor specification, including viscosity, chemistry, dye content and electric-compressor requirements. Measure oil with clean dedicated equipment and add only the calculated replacement quantity; both under- and over-oiling can affect lubrication and heat transfer.
PAO 68, dye-bearing oils and electric compressors
PAO 68 RL897 with dye is a different oil family from PAG. Treat its RL897 identifier, ISO grade, dye and stated refrigerant/system coverage as a complete specification. Do not use it merely because its bottle is available or because a workshop wants one oil for several systems. Compatibility with the remaining original lubricant, seals and compressor must be documented.
High-voltage electric compressors add an insulation requirement that cannot be inferred from viscosity. Elke's official selection page separately identifies POE ISO 80 where an electric-compressor or dielectric lubricant is required, which shows why ordinary PAG or PAO wording is insufficient. Follow the exact vehicle procedure, use clean dedicated injectors and never contaminate electric-compressor oil with residue from a conventional system.
UV dye as a diagnostic aid
Elke describes UV additive as a small quantity of fluorescent contrast liquid circulated with refrigerant so leakage sites can be found with a suitable lamp. The listed 250 ml product is titled for R134a and R1234yf, but the correct dose per system and compatibility with its lubricant still come from the current technical instructions. Dye identifies evidence of leakage; it does not seal or quantify the fault.
Check for old dye before adding more, because previous residue can produce misleading traces. Clean the suspected area with an approved remover, run the system only when safe, then inspect under the specified UV light while wearing suitable UV eye protection. Follow pipework, condensate and airflow paths so carried dye is not mistaken for the origin. Once found, repair and prove the system through the approved leak-test route.
Leak stop and micro-leak boundaries
Three titles concern leak stop or sealer: an R1234yf 40 ml product, an R134a treatment and a 30 ml hybrid/electric syringe supplied with two refrigerant hoses. Elke's official material describes its leak-stop family for micro-leaks and states compatibility with R134a and R1234yf formats. That narrow description should not be extended to fractured pipes, damaged condensers, failed seals, compressor faults or unidentified loss.
Confirm that the vehicle maker and every recovery, charging and leak-detection machine involved accepts the exact sealer. Some workshops or equipment procedures prohibit systems containing sealer because it can contaminate service circuits. Use the complete specified quantity and connector only through the Elke method; never choose a hose by what can be made to fit. If the leak is accessible, a documented mechanical repair and verified pressure integrity remain the controlled route.
Flushing, evacuation and clean service practice
The five-litre Elke flushing agent is for a defined cleaning process after refrigerant recovery and component isolation. Determine which lines and heat exchangers may be flushed and which items must be removed or replaced under the vehicle procedure. Do not circulate flushing chemical through a compressor, accumulator, receiver-drier, expansion device or service machine unless the exact instructions explicitly support it.
Use compatible closed flushing equipment, collect all outgoing liquid and continue the documented drying procedure until no solvent or contamination remains. Fit specified new seals and moisture-control components, then evacuate for the required time and confirm vacuum stability by the service method. Charge the identified refrigerant by mass with dedicated couplers, perform leak and performance checks, label the work and send recovered refrigerant and waste chemicals through authorised routes.
From identification to a checked result
| Stage | Good practice for this range | Mistake to avoid |
|---|---|---|
| Identify | Read the label and identify refrigerant, compressor and existing contents | Assuming the connector proves R134a or R1234yf |
| Specify | Confirm oil family, viscosity, dielectric need, quantity and additive policy | Choosing PAG 46, PAG 100, PAO or universal by convenience |
| Recover | Use dedicated approved equipment and contain refrigerant and oil | Venting gas or opening a pressurised circuit |
| Repair | Trace the fault, replace or clean only by the documented procedure | Using dye or sealer to conceal a major leak |
| Commission | Evacuate, charge by mass, leak-test, check performance and label | Adding refrigerant by pressure or temperature impression alone |
Record every Elke product code, oil quantity, dye or sealer dose and service-machine route. That record protects the next technician from unknowingly combining incompatible refrigerant, lubricant or additive and is especially important when an electric compressor is present.
Reading real Elke references
The Elke names below are examples from the current range and show why the complete description matters. They are not universal Elke recommendations and should not be treated as a fitment list. Within Elke, a shared family word can conceal a different dimension, connector, material, pack format, operating condition or installation side.
| Example listing | What to verify beyond the name |
|---|---|
| Hybrid & Electric Leak Stop Syringe With R134a & HFO1234yf Hoses | Electric-compressor approval, refrigerants, exact dose, hoses and equipment acceptance |
| Elke R134a Pag46 Oil - 250ml | PAG 46 approval, R134a system and measured oil quantity |
| Elke R134a Pag46 Oil - 1 Litre | PAG 46, container volume, moisture control and unopened storage |
| Elke R134a Pag46 Oil with dye - 1 Litre | PAG 46 plus dye, previous dye level and exact quantity |
| Elke R134a Pag100 Oil - 250ml | PAG 100 specification, R134a system and compressor requirement |
| Elke HFO1234yf Pag46 Oil - 250ml | R1234yf, PAG 46 and compressor/electrical design |
| Elke PAO68 RL897 Oil with dye - 1 Litre | PAO 68 RL897, dye, remaining oil and approved system |
| Elke Flushing Agent - 5 Litre | Flushable components, recovery, drying and waste route |
The names contain vital boundaries—R134a, R1234yf, PAG 46, PAG 100, PAO 68, dye, flushing agent and leak sealer. Preserve all of them when ordering. A shortened note such as ‘Elke oil’ or ‘universal A/C product’ is not a safe specification.
Common errors around Elke products
- Choosing A/C oil by refrigerant alone without checking the compressor specification.
- Substituting PAG 46, PAG 100, PAO 68 or universal PAG for one another.
- Using conventional PAG in an electric compressor that requires a specified dielectric lubricant.
- Adding oil without calculating the quantity recovered or retained after component replacement.
- Overdosing UV dye or treating fluorescence as proof of the exact leak origin.
- Using leak sealer for a large, structural or unidentified system fault.
- Introducing sealer into equipment whose manufacturer prohibits it.
- Venting refrigerant or flushing unsupported components with the system assembled.
Elke questions and answers
Q: What Elke products are represented here?
A: The range covers A/C lubricants, dye-bearing oils, UV dye, flushing agent and refrigerant-specific leak products.
Q: Is PAG 46 interchangeable with PAG 100?
A: No. Match the exact viscosity and chemistry required by the vehicle or compressor maker.
Q: Can PAO 68 replace PAG oil?
A: Only where the exact system documentation approves that PAO product and its compatibility with remaining oil.
Q: Does Universal PAG fit every A/C system?
A: No. Universal is product positioning, not permission to override a compressor's specified lubricant.
Q: Can ordinary PAG be used in an electric compressor?
A: Do not assume so; electrically driven compressors may require a specified high-dielectric lubricant and dedicated tools.
Q: How much compressor oil should be added?
A: Use the vehicle procedure, recovered-oil measurement and replaced-component allowances rather than estimating from bottle size.
Q: What does UV dye do?
A: It circulates as a fluorescent tracer to reveal leakage evidence under a suitable UV lamp; it does not repair the leak.
Q: Can more dye make a leak easier to find?
A: Excess dye can contaminate and confuse diagnosis, so use only the exact system dose.
Q: When is Elke Leak Stop relevant?
A: The official scope is micro-leaks, subject to vehicle and service-equipment acceptance of the exact product.
Q: Can one hose be used for both refrigerants?
A: Use only the dedicated, identified adapter and process specified for the product and prevent cross-contamination.
Q: Can the complete A/C system be flushed?
A: No general assumption is safe; recover first and follow the vehicle procedure for flushable, removed and replaced components.
Q: Who should service the system?
A: A trained technician using approved identification, recovery, evacuation and charging equipment should control the work.
