R-32 20LB(Difluoromethane)

R-32 Refrigerant — The Efficient, Single-Component Alternative for Modern HVAC/R Systems Tulstar Products supplies virgin R-32 (Difluoromethane, HFC-32) refrigerant in bulk quantities for HVAC/R contractors, distributors, and equipment manufacturers. As a single-component HFC — not a blend — R-32 delivers consistent performance with no fractionation risk during charging, storage, or leaks, making it a reliable option for split systems, mini-splits, and heat pumps designed for its use. With over 35 years distributing refrigerants, industrial chemicals, and specialty gases, Tulstar sources R-32 through vetted supply channels and ships from our Tulsa, OK facility with full EPA Section 608 compliance verification on every order. Why R-32? Higher efficiency — R-32's thermodynamic properties allow for smaller charge sizes and improved system efficiency compared to blended alternatives like R-410A. Simplified servicing — As a single-component refrigerant, R-32 doesn't fractionate, so vapor and liquid composition stay consistent throughout the system's life — no more guessing about blend ratios after a leak. Lower global warming potential — R-32 carries a GWP of roughly 675–771 (depending on assessment methodology), a meaningful reduction versus R-410A's GWP of ~2,088. Reduced refrigerant charge — Systems designed for R-32 typically require less refrigerant by weight than equivalent R-410A systems, lowering both cost and environmental impact per unit. Zero ozone depletion potential (ODP) — Like other HFCs, R-32 does not contribute to ozone layer depletion. Classification & Handling R-32 is classified as an A2L refrigerant (mildly flammable, lower toxicity) under ASHRAE Standard 34. This requires technicians to follow A2L-specific handling, recovery, and installation practices. All purchasers must provide valid EPA Section 608 certification prior to fulfillment, per federal handling requirements.
