BSM RJT Union O-Ring

BSM RJT union O-rings are essential sealing components used to create a hygienic, leak-resistant seal within RJT (Ring Joint Type) union assemblies. Installed between the mating faces of the RJT union components, the O-ring ensures a secure seal while maintaining a clean internal profile suitable for sanitary process pipework. These seals are widely used in food, beverage, dairy, pharmaceutical, and other hygienic processing systems where cleanliness, reliability, and repeatable sealing performance are critical.

Correct O-ring material selection is vital to ensure compatibility with process conditions. Seal materials are chosen based on operating temperature, chemical exposure, pressure, and cleaning regimes such as clean-in-place (CIP) or sterilise-in-place (SIP). EPDM O-rings are commonly specified for hygienic applications due to their excellent resistance to hot water, steam, and many alkaline and acidic cleaning chemicals. They perform well in regular wash-down and CIP cycles and are a standard choice in many food and beverage systems.

Teflon (PTFE) O-rings are also available in the sizes shown and are selected where superior chemical resistance or higher temperature capability is required. PTFE is highly inert and suitable for aggressive media, solvents, or processes where elastomer compatibility may be a concern. Its low friction characteristics also support consistent assembly and disassembly of RJT unions.

The smooth, accurately sized O-ring ensures even compression when the union is tightened, helping to maintain a reliable hygienic seal and minimise the risk of leaks. Proper installation and correct sizing are essential to ensure optimal performance and long service life.

BSM RJT union O-rings are available in a range of standard sizes to suit common RJT union dimensions. To ensure proper sealing, compatibility, and hygienic performance, select the O-ring size that matches the RJT union size used in your system.
