Chemours Opteon™ XL41 R-454B Refrigerant is a lower-GWP HVAC refrigerant developed for new air-conditioning, heat-pump, and compatible chiller equipment specifically designed for R-454B.

Supplied in a 20 lb cylinder, Opteon XL41 is a professional refrigerant option for HVAC contractors, service technicians, mechanical contractors, facility teams, and commercial buyers working with newer R-454B equipment.

R-454B combines R-32 and R-1234yf to provide operating characteristics similar to R-410A while substantially reducing refrigerant global warming potential. It is classified as an A2L refrigerant and requires equipment, service procedures, and tools appropriate for mildly flammable refrigerants.

R-454B is not a universal or drop-in replacement for R-410A. Always confirm that the equipment nameplate specifies R-454B and follow the equipment manufacturer's installation and service instructions.

What Is Opteon XL41 R-454B?

Opteon XL41 is Chemours' branded R-454B refrigerant.

R-454B is a zeotropic refrigerant blend containing:

  • 68.9% R-32

  • 31.1% R-1234yf

Chemours developed Opteon XL41 as a lower-GWP alternative to R-410A for new HVAC equipment designs.

It has zero ozone depletion potential and significantly lower global warming potential than R-410A. It also provides thermodynamic properties that allow equipment manufacturers to design residential and commercial HVAC systems with operating characteristics similar to R-410A equipment.

Because R-454B is an A2L refrigerant, systems using it are engineered around specific safety and installation requirements.

R-454B Refrigerant for New HVAC Equipment

R-454B is increasingly used in newer residential and light-commercial HVAC equipment as manufacturers transition away from higher-GWP R-410A.

Opteon XL41 may be used in compatible equipment such as:

  • Residential central air conditioners

  • Residential heat pumps

  • Light-commercial air-conditioning systems

  • Packaged HVAC equipment

  • Rooftop units designed for R-454B

  • Direct-expansion air-conditioning equipment

  • Compatible chillers

  • Other HVAC equipment specifically designed and listed for R-454B

Application type alone does not confirm compatibility.

Always verify the refrigerant designation on the equipment nameplate before charging or servicing a system.

Opteon XL41 R-454B vs. R-410A

R-454B was developed as a lower-GWP alternative to R-410A for new equipment designs.

Chemours reports an AR4 GWP of approximately 466 for Opteon XL41, compared with 2,088 for R-410A. This represents a substantial reduction in refrigerant global warming potential.

However, R-454B and R-410A are different refrigerants.

R-410A carries an A1 safety classification, while R-454B is classified as A2L. The A2L classification means R-454B has mild flammability characteristics that must be addressed through appropriate equipment design, installation requirements, service procedures, and technician practices.

The lower GWP of R-454B does not make it interchangeable with R-410A in existing equipment.

Can R-454B Replace R-410A in an Existing System?

R-454B should not be used as a field drop-in replacement for R-410A in existing equipment.

Chemours describes Opteon XL41 as a refrigerant intended to replace R-410A in new equipment designs. EPA likewise lists R-454B for new residential and light-commercial air-conditioning and heat-pump equipment subject to applicable use conditions.

Equipment designed for R-454B incorporates safety and engineering requirements associated with A2L refrigerants.

These may include requirements involving:

  • Refrigerant charge limits

  • Electrical components

  • Ignition-source mitigation

  • Leak detection or mitigation

  • Equipment construction

  • Installation procedures

  • Service equipment

  • Ventilation

  • Applicable codes and standards

If an existing system specifies R-410A, technicians should continue to follow the equipment manufacturer's refrigerant requirements rather than substituting R-454B.

R-454B Is an A2L Refrigerant

Chemours Opteon XL41 carries an A2L safety classification.

A2L refrigerants are classified as lower toxicity with lower flammability. This differs from A1 refrigerants such as R-410A.

HVAC technicians servicing R-454B equipment should follow the equipment manufacturer’s procedures, Chemours Safety Data Sheet, applicable codes and standards, and requirements for A2L refrigerants.

Tools and service equipment should be appropriate for the refrigerant and application.

Never assume that equipment or procedures used for an A1 refrigerant are automatically suitable for R-454B.

Low-GWP Alternative to R-410A

One of the primary reasons R-454B has been adopted in new HVAC equipment is its substantially lower GWP compared with R-410A.

Chemours reports an AR4 GWP of approximately 466 for Opteon XL41, representing about a 78% reduction compared with R-410A.

This helps equipment manufacturers meet current refrigerant-transition requirements while continuing to design high-capacity air-conditioning and heat-pump equipment.

Actual equipment efficiency, capacity, electricity consumption, and operating performance depend on system design and operating conditions. These results should not be assumed solely from the refrigerant selected.

R-454B Temperature Glide

R-454B is a zeotropic refrigerant blend and has a small temperature glide.

Technicians should use pressure-temperature data specifically developed for R-454B and follow the equipment manufacturer's service procedures when checking:

  • Refrigerant pressures

  • Evaporating temperature

  • Condensing temperature

  • Superheat

  • Subcooling

  • Refrigerant charge

Using data for R-410A or another refrigerant can result in incorrect system readings.

20 lb Chemours Opteon XL41 Cylinder

The 20 lb Chemours Opteon XL41 R-454B cylinder provides a practical refrigerant quantity for professional HVAC contractors and service companies working with compatible R-454B systems.

Before using the cylinder, verify:

  • Opteon XL41 branding

  • R-454B refrigerant designation

  • Cylinder condition

  • Safety Data Sheet

  • Equipment nameplate

  • Required refrigerant charge

  • Service-tool compatibility

  • Equipment manufacturer procedures

Store and transport the cylinder according to Chemours documentation and applicable regulations for A2L refrigerants.

Is R-454B an Automotive Refrigerant?

R-454B should not be marketed as a general automotive A/C refrigerant.

Chemours positions Opteon XL41 for stationary air-conditioning, heat-pump, and compatible chiller applications. EPA's R-454B approval likewise covers specified new stationary HVAC equipment subject to applicable use conditions.

Automotive air-conditioning systems use refrigerants approved specifically for MVAC applications.

Always use the refrigerant specified by the vehicle or equipment manufacturer.

Who Can Purchase R-454B Refrigerant?

Federal refrigerant sales restrictions apply to R-454B intended for stationary air-conditioning and heat-pump equipment.

Purchasers generally must be EPA Section 608 certified technicians, qualifying employers or authorized representatives of certified technicians, qualifying refrigerant resellers, or other purchasers permitted under applicable federal requirements.

Section 609 certification applies to refrigerants acceptable for motor-vehicle air-conditioning applications and does not by itself authorize the purchase of refrigerant intended for stationary HVAC equipment.

Buyers should confirm applicable federal, state, local, and destination requirements before ordering.
