R417A Refrigerant Gas
R417A is a zeotropic retrofit refrigerant blend used in selected R22 stationary air-conditioning and medium-temperature refrigeration applications.
The finished blend is classified A1 and has zero ozone depletion potential, but retrofit suitability must be checked against the actual equipment, lubricant and OEM guidance.
Cylinder supply is available subject to current order specifications. Confirm filling weight, packaging configuration and destination requirements before ordering.

Description
R417A Refrigerant Gas
R417A is a zeotropic refrigerant blend with a nominal composition of 46.6% R125, 50% R134a and 3.4% R600a by mass. It was developed for selected R22 retrofit applications.
Industry product guidance positions R417A mainly for stationary air conditioning and medium-temperature commercial refrigeration. Its small hydrocarbon fraction contributes to lubricant-management behavior, but system condition and oil return still require technical review.
R417A has zero ozone depletion potential and an A1 safety classification. Published AR4 product data list a 100-year GWP of 2,346, so it should be understood as an installed-base transition option rather than a modern low-GWP endpoint.

Key R417A Refrigerant Properties
Key identification and retrofit-reference data for R417A.
R417A Technical Specifications
R417A should be evaluated as a multi-component retrofit blend rather than as a pure refrigerant.
| Refrigerant Designation | R417A |
|---|---|
| Nominal Composition | R125 / R134a / R600a = 46.6 / 50 / 3.4 mass % |
| Refrigerant Type | Zeotropic retrofit blend |
| Ozone Depletion Potential (ODP) | 0 |
| 100-Year Global Warming Potential | 2,346 — IPCC AR4 basis |
| ASHRAE Safety Class | A1 |
| Transport Hazard Class | Class 2.2 |
Use the current supplier P-T data and SDS when charging or servicing R417A. Blend composition, lubricant behavior and system performance cannot be derived safely from R22 data alone.
Typical R417A Applications
R417A is principally a service and retrofit refrigerant for selected installed R22 systems.
Residential Air Conditioning
Selected legacy direct-expansion R22 air-conditioning systems may be candidates for an engineered R417A retrofit.
Commercial Air Conditioning
R417A is used in selected stationary commercial AC retrofit projects where system and compressor requirements are satisfied.
Medium-Temperature Refrigeration
Commercial refrigeration and food-service equipment operating in medium-temperature ranges represent an established R417A retrofit context.
See Air Conditioning Refrigerants and Commercial Refrigeration for broader application research.
R417A Safety and Handling Considerations
R417A is A1, but retrofit work adds system-condition, blend-handling and lubricant considerations beyond the basic safety label.
Blend Charging
Follow the current supplier charging procedure for R417A and use refrigerant-specific pressure-temperature data.
Lubricant Review
Industry guidance lists compatibility with mineral oil, alkylbenzene and POE, but actual oil return and compressor requirements remain system-specific.
Recovery & Ventilation
Recover refrigerant during service, prevent uncontrolled releases and provide ventilation for work in enclosed areas.
R417A may reduce the amount of system modification needed in some R22 retrofits, but compressor approval, oil return, expansion device behavior, seals, charge and operating performance still need to be checked.
R417A Product Specification & Documentation
The supplier documentation provided for this project confirms R417A as a commercial refrigerant product, but it does not support publishing one universal cylinder fill weight.
| Refrigerant Identity | R417A |
|---|---|
| Nominal Composition | 46.6% R125 / 50% R134a / 3.4% R600a |
| Supplied Form | Liquefied compressed refrigerant blend |
| Packaging Specification | Confirm current cylinder fill weight and valve configuration per order |
R417A Refrigerant Packaging Options
R417A is supplied in refrigerant cylinders, with exact fill weight and packaging configuration confirmed for the destination and order.
| Packaging Type | Reference Size | Supply Note |
|---|---|---|
| Cylinder Supply | Confirm per order | Exact filling weight and valve configuration should be specified in the quotation / order documentation |
No single package size is published here because the supplied source material does not establish one universal current R417A fill weight. Confirm the actual cylinder specification before ordering.
R417A Is an R22 Retrofit and Installed-Base Option
R417A is relevant when an existing R22 system is being evaluated for continued service rather than immediate equipment replacement.
Its role should be assessed against other R22 retrofit routes, system age, remaining asset life, compressor condition, energy performance and local refrigerant policy.
- Use case: selected R22 direct-expansion AC and medium-temperature refrigeration retrofits.
- System review: verify lubricant management, capacity, controls and component condition.
- Long-term planning: high GWP means R417A is generally a transition refrigerant, not a future low-GWP platform.
Do not choose R417A solely from refrigerant name or application overlap. Follow OEM, compressor and refrigerant-supplier retrofit guidance for the specific equipment.
R417A Refrigerant Frequently Asked Questions
What is R417A refrigerant?
R417A is a zeotropic refrigerant blend used mainly as an R22 retrofit option in selected stationary air-conditioning and medium-temperature refrigeration systems.
What is R417A made of?
The nominal composition used here is 46.6% R125, 50% R134a and 3.4% R600a by mass.
What is the GWP of R417A?
Published AR4 product data list R417A at a 100-year GWP of 2,346.
Is R417A flammable?
The finished refrigerant is classified A1.
Can R417A replace R22 directly?
Do not assume a universal drop-in. Retrofit suitability depends on compressor approval, lubricant, expansion device, seals, charge and operating conditions.
What package size is available for R417A?
Cylinder supply is available, but the exact fill weight and valve configuration should be confirmed for the current order rather than inferred from a generic listing.
Product information on Refrigerants.net is provided for product identification, comparison and B2B purchasing research. Final refrigerant specification, packaging, availability, transport requirements, permitted use and equipment compatibility should be confirmed against current product documentation, SDS, OEM requirements and applicable regulations before purchase or use.
