Built for the correct system—not every system
Common compatible work
- Compatible residential and commercial air-conditioning systems
- Heat-pump equipment labeled for R407C
- Approved medium-temperature refrigeration
- Engineered R22 retrofit projects with required component and lubricant changes
Confirm before ordering
- The system is factory-approved for R407C or has a documented retrofit plan
- The selected lubricant is compatible and oil-return requirements are satisfied
- Controls and the expansion device are correctly set for the blend glide
- Pressure-temperature calculations use the correct dew and bubble values
Plan the charge before opening the valve
Account for glide
Use the correct dew-point or bubble-point value for superheat and subcooling calculations.
Convert completely
For retrofits, recover the existing charge and complete every required oil, seal, label and control change before commissioning.
Compatibility is mandatory
R407C is not a direct top-off for R22 or any other refrigerant. Never mix it into an existing R22 charge. A retrofit requires documented equipment suitability, full refrigerant recovery and verification of lubricant, metering and control compatibility.

Restricted refrigerant sale
Bulk refrigerant sales in the United States are restricted. Proof of the applicable Section 608 or Section 609 technician certification—or documentation that the purchaser employs a properly certified technician—may be required before fulfillment. The purchaser is responsible for satisfying federal, state and local rules for purchase, transport, storage and use.
S
Handling and storage
Keep the cylinder upright, secured and protected from high heat or damage. Store in a cool, dry, ventilated location and follow the safety data sheet. Refrigerant can displace oxygen, cause cold burns and create dangerous pressure if mishandled. Never intentionally vent refrigerant.
