With a GWP of just 290 — 80% lower than R134A's GWP of 1,430 — RS-20 allows automotive shops, commercial refrigeration operators, and fleet service centers to continue servicing existing R134A equipment with a dramatically more climate-friendly refrigerant, and with no hardware changes required. Refrigerant Inc stocks genuine RS-20 in 24 lb cylinders with free shipping to all 48 continental states.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Makes RS-20 Different From Other R134A Replacements\u003c\/h2\u003e\n\n\u003cp\u003eRS-20 (R480A) is a unique blend of CO2, R1234ze, and R227ea — a non-flammable, non-ozone-depleting combination that delivers performance equivalent to R134A while achieving a GWP of 290.
