R422B Refrigerant 25lb Cylinder

R422B 25lb Refrigerant Cylinder – R-22 Retrofit for Houston HVAC

Note on this listing: this product was previously filed under Accessories & Tools in our catalog.
It is a refrigerant, not a tool, and has been recategorized under HVAC Refrigerants so it shows up
correctly for techs searching for an R-22 replacement blend.

Refrigerants Center stocks virgin, factory-sealed R-422B in Houston for HVAC and refrigeration
contractors retrofitting existing R-22 equipment without a full system replacement.

How R-422B Works as an R-22 Retrofit

R-422B is an HFC blend designed to closely match R-22’s pressure and capacity behavior, making it a
practical retrofit option for many existing medium- and low-temperature refrigeration systems. It
carries zero ozone depletion potential and is generally compatible with the mineral oil already present
in many older R-22 systems, which can simplify the retrofit process compared to blends requiring a full
oil change.

Where This Gets Used Around Houston

Commercial refrigeration contractors and HVAC techs servicing older display cases, walk-in coolers,
and light commercial AC equipment across the Houston metro use R-422B when a customer wants continued
service life from R-22 equipment without the cost of full replacement.

Refrigerants Center keeps this cylinder in stock at our Houston warehouse, with same-day and next-day local delivery routed through Pearland and Friendswood. Techs working across Pasadena and Baytown, Katy and Cypress, and Sugar Land and Missouri City order from us just as often, since one Houston-based supplier covers the whole metro without the wait times of national distributors. Commercial refrigeration accounts across the region turn to R-422B specifically for retrofit jobs that need to stay online with minimal downtime.

Compliance and Retrofit Notes

All cylinders ship DOT-compliant and are sold in accordance with EPA Section 608/609 rules. Refrigerants Center verifies technician certification on regulated refrigerant orders before dispatch from our Houston warehouse. Always follow the manufacturer’s retrofit procedure, including checking for
required gasket or seal compatibility, before charging R-422B into a converted system.

Comparing Other R-22 Retrofit Options

Depending on the equipment and oil type, our
R-438A retrofit refrigerant is another commonly
used R-22 replacement worth comparing against your system’s approved refrigerant list.
