Chemours d15440181 R-422B Refrigerant 25 Pounds Hfc

Product Description

The CHEMOURS d15440181 is a 25-pound cylinder of R-422B refrigerant, an HFC-based blend sold under the NU-22B designation. R-422B is a retrofit refrigerant designed to replace R-22 in existing air conditioning and light commercial refrigeration systems without requiring an oil change in many applications. Licensed HVAC technicians use this refrigerant during service calls on older R-22 equipment where full system conversion or compressor replacement is not yet scheduled. The 25-pound cylinder size is suited for shop stock or field service on multiple units.

R-422B is applied in residential and light commercial air conditioning systems originally charged with R-22. It is intended for use in direct-expansion systems where a technician needs a service refrigerant that operates within pressure and capacity ranges compatible with R-22 equipment. This product is sold in a single 25-pound cylinder per unit of measure.

Key Features

• 25-pound cylinder of R-422B HFC refrigerant blend
• Marketed as NU-22B, a retrofit alternative to R-22

Installation Notes

R-422B must be handled and recovered by an EPA Section 608 certified technician using certified recovery equipment. Always recover existing refrigerant before introducing R-422B and verify system operating pressures against published R-422B pressure-temperature charts. Do not mix refrigerants in a system or cylinder. Inspect for leaks after recharge before returning equipment to service.
