Description
Engineered for more demanding environments, this FKM O-ring provides a high performance sealing solution for press fit systems exposed to elevated temperatures and aggressive media. It is particularly suited to applications involving oils, fuels, and industrial fluids where standard sealing materials may not perform effectively. Manufactured from durable FKM material, it offers excellent resistance to heat, chemicals, and hydrocarbons, ensuring long term reliability in challenging operating conditions. Its ability to maintain sealing integrity at temperatures up to 200°C makes it ideal for specialised systems such as solar thermal, industrial processing, and compressed air with oil.
Designed for seamless integration with PremPress fittings, it works in conjunction with the M-profile press system to create a secure, leak-free joint. It also supports the system’s built-in leak detection capability, ensuring any unpressed connections are clearly identified during pressure testing. Produced to meet the high standards, this O-ring delivers dependable performance where higher specification sealing is required.
An EPDM alternative is available for standard water and heating applications.
