iGas R-507 Refrigerant is supplied in a 25 lb factory-sealed cylinder for professional service of compatible low- and medium-temperature commercial refrigeration equipment.

R-507, also commonly designated R-507A, is an HFC refrigerant blend used in commercial and industrial refrigeration applications where equipment specifically requires R-507. It has historically been associated with supermarket refrigeration, freezers, cold-storage equipment, food-processing refrigeration, and other demanding low-temperature applications.

This iGas R507 25 lb refrigerant cylinder is a practical option for refrigeration contractors, HVAC-R technicians, facility maintenance teams, cold-storage operators, foodservice businesses, and other qualified commercial buyers maintaining compatible equipment.

Always verify the refrigerant specified on the equipment nameplate and follow the equipment manufacturer's service instructions before charging or servicing a refrigeration system.

R507 Refrigerant for Commercial Refrigeration

R-507 has been used extensively in medium- and low-temperature commercial refrigeration systems.

Depending on the equipment design and applicable regulations, existing R-507 systems may be found in applications such as:

  • Commercial freezers

  • Walk-in freezers

  • Walk-in coolers

  • Supermarket refrigeration

  • Cold-storage equipment

  • Food-processing refrigeration

  • Industrial refrigeration

  • Refrigerated display equipment

  • Other compatible medium- and low-temperature refrigeration systems

Application type alone does not establish refrigerant compatibility.

Always verify the refrigerant specified by the equipment manufacturer before adding R-507.

What Is iGas R-507 Refrigerant?

R-507 is an HFC refrigerant composed of equal amounts of R-125 and R-143a.

Unlike many zeotropic refrigerant blends, R-507 behaves as an azeotropic or near-azeotropic blend with essentially no meaningful temperature glide during normal refrigeration service.

R-507 has zero ozone depletion potential and carries an A1 safety classification under the applicable refrigerant safety standard.

It was originally developed as a non-ozone-depleting alternative to R-502 for medium- and low-temperature refrigeration applications.

Today, however, R-507 has a relatively high global warming potential compared with newer commercial refrigeration refrigerants. Its strongest role in the current market is servicing compatible existing equipment rather than serving as a general-purpose refrigerant for new systems.

Is R507 the Same as R507A?

R-507 and R-507A are commonly used to refer to the same standardized refrigerant blend.

The refrigerant contains:

  • 50% R-125

  • 50% R-143a

Technicians and buyers may encounter both R-507 and R-507A terminology in equipment documentation, refrigerant catalogs, pressure-temperature charts, and regulatory information.

Always verify the refrigerant designation on the cylinder and equipment nameplate before use.

R507 vs. R404A

R-507 and R-404A have historically been used in many similar commercial refrigeration applications, but they are not the same refrigerant.

R-507 consists of R-125 and R-143a in equal proportions, while R-404A contains R-125, R-143a, and R-134a.

Both are high-GWP HFC refrigerants and have been widely used in low- and medium-temperature refrigeration.

Technicians should not automatically substitute R-507 for R-404A or R-404A for R-507 solely because their applications and operating characteristics may be similar.

Always follow the equipment manufacturer's refrigerant specifications and approved service procedures.

Can R507 Replace R502?

R-507 was originally developed as a non-ozone-depleting replacement for R-502 in certain refrigeration applications.

However, that historical application should not be interpreted as permission to retrofit any R-502 system to R-507 today.

Current U.S. refrigerant rules restrict R-507 in several categories of new and retrofit refrigeration equipment. Any refrigerant conversion should therefore be evaluated based on:

  • Current EPA requirements

  • Equipment manufacturer recommendations

  • Compressor compatibility

  • POE lubricant requirements

  • Expansion-device operation

  • Refrigerant charge

  • Control settings

  • System operating conditions

  • Applicable state and local rules

For current service work, R-507 is most appropriately used where an existing compatible system already specifies or contains R-507 and continued service is permitted.

R507 Refrigerant and POE Lubricant

R-507 is commonly used with polyolester, or POE, lubricant.

Lubricant selection is an important part of refrigeration service because compressor reliability and oil return depend on using the lubricant approved for the equipment and refrigerant.

Never assume lubricant compatibility based solely on the refrigerant designation.

Before performing service, confirm:

  • Compressor manufacturer requirements

  • Existing lubricant type

  • Required oil viscosity

  • System piping configuration

  • Refrigerant and lubricant compatibility

Follow the compressor and equipment manufacturer's specifications whenever lubricant replacement or adjustment is necessary.

Is R507 Still Used?

Yes. R-507 remains relevant for servicing existing commercial refrigeration equipment designed for it.

However, R-507 has a high global warming potential, and current U.S. regulations increasingly restrict high-GWP HFC refrigerants in new commercial refrigeration equipment.

This means R-507 should not be positioned as a future-proof refrigerant or the preferred choice for new refrigeration installations.

Existing compatible equipment can still require R-507 for maintenance and repair where permitted by applicable regulations.

For owners of existing R-507 systems, refrigerant selection should be based on equipment specifications, current regulations, system condition, and long-term maintenance planning.

Alternatives to R507 Refrigerant

Commercial refrigeration systems are increasingly moving toward refrigerants with lower global warming potential.

Depending on the equipment and application, refrigerants such as R-448A or R-449A may be evaluated as alternatives in certain situations.

These refrigerants are not direct substitutes that can simply be mixed with or added to R-507.

A conversion may require changes to:

  • Refrigerant charge

  • Expansion devices

  • Controls

  • Pressure settings

  • Compressor operating conditions

  • System programming

  • Service procedures

Always use a manufacturer-approved retrofit procedure and recover the existing refrigerant before introducing a different refrigerant.

Factory-Sealed iGas R507 25 lb Cylinder

This product is supplied as a factory-sealed 25 lb iGas R-507 cylinder, providing professional refrigeration contractors and maintenance teams with a convenient refrigerant quantity for compatible service applications.

Before use, verify:

  • Cylinder condition

  • Product label

  • Safety Data Sheet

  • Service connection

  • Equipment compatibility

  • Required refrigerant charge

Store and transport refrigerant cylinders in accordance with product instructions and applicable regulations.

R507 Safety and Professional Handling

R-507 carries an A1 safety classification, meaning it is classified as lower toxicity and does not propagate flame under the applicable refrigerant safety standard.

R-507 is still a liquefied gas stored under pressure and requires appropriate professional handling.

Technicians should follow:

  • The iGas Safety Data Sheet

  • Equipment manufacturer instructions

  • Applicable refrigerant recovery requirements

  • Federal, state, and local regulations

  • Proper cylinder transportation and storage procedures

  • Appropriate personal protective equipment requirements

Use professional refrigeration charging, recovery, and service equipment suitable for the refrigerant and equipment being serviced.

Do not intentionally vent R-507 into the atmosphere.

Who Can Purchase R507 Refrigerant?

Federal refrigerant sales restrictions apply to R-507 intended for stationary refrigeration equipment.

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

Section 609 certification applies to motor-vehicle air-conditioning applications and does not by itself authorize a purchaser to buy R-507 intended for stationary commercial refrigeration.

State and local restrictions may also apply.
