Product composition: Petroleum Gases, Liquefied. "THIS PRODUCT IS NOT HFC-R134A" Restore your A/C system's performance with Enviro-Safe R134a Industrial Replacement Refrigerant — a powerful, eco-conscious alternative to traditional R12, R134a, and R1234YF refrigerants. Each 8 oz can equals 16 oz of R12 or R1234YF and 21 oz of standard R134a, giving you more cooling power with less product. This refrigerant operates at lower head pressures than standard R134a, helping reduce compressor strain and improve system efficiency. Featuring a piercing can design, this product works seamlessly with standard charging equipment, making it ideal for DIYers and professionals alike. ✅ U.S. Customers: Per EPA regulations, R12 systems must be properly retrofitted with approved fittings and labels before use. 🍁 Canadian Customers: May use this product as a direct substitute for R12, R134a, or R1234YF systems without retrofit. Enviro-Safe is made in the USA, non-ozone depleting, and designed to deliver fast, cold air with reliable performance. ⚠️ Always follow local regulations and safety guidelines when servicing A/C systems.
