Is BURGACLIP Sealing O-Ring compatible with all common refrigerants used in modern HVAC systems?

BURGACLIP Sealing O-Ring is formulated from hydrogenated nitrile rubber (HNBR) and explicitly designed for freon applications in air conditioning fittings. HNBR offers excellent resistance to many common refrigerants, lubricating oils, and high pressures used in modern HVAC systems, and its wide temperature range (-30°C to +150°C) supports durable performance. However, compatibility with "all common refrigerants" cannot be guaranteed absolutely. HNBR is broadly compatible with CFCs, HCFCs (e.g., R-22), HFCs (e.g., R-134a, R-410A) and many blended refrigerants and their oils, which makes BURGACLIP Sealing O-Ring suitable for the vast majority of modern systems. Caution is advised with some new low-GWP refrigerants, certain synthetic ester oils, or specialty blends—these can have different chemical compatibilities and may require specific elastomers (e.g., EPDM, FKM) or manufacturer confirmation. Recommendation: verify the exact refrigerant and oil used in the system and consult BURGACLIP technical data or the supplier for confirmed compatibility with that specific refrigerant/oil combination before installation.

Does the BURGACLIP Sealing O-Ring maintain its sealing performance under high-pressure conditions common in commercial HVAC systems?

Yes. The BURGACLIP Sealing O-Ring is formulated and specified to maintain sealing performance under the high-pressure conditions common in commercial HVAC systems. Made from premium hydrogenated nitrile rubber (HNBR), it delivers excellent resistance to refrigerants, oils and elevated pressures typical of freon applications in air-conditioning fittings. Its wide operating temperature range (-30°C to +150°C) and robust material properties ensure dimensional stability and long-term elasticity under both thermal extremes and pressure cycling, minimizing leak risk and reducing maintenance. In short, BURGACLIP Sealing O-Ring is engineered for reliable, durable sealing in demanding commercial HVAC environments.
