Trelleborg Teguflex P HO Flanged Rubber Flexible Connectors
Key Information
Trelleborg Teguflex P HO bellows are a compact high-performance moulded rubber expansion joint developed for oil and gas applications involving oils, water mixed oils, and compressed air/oil systems operating at temperatures up to 120°C. Manufactured with a fluted HNBR inner tube, aramid reinforcement, and an oil and weather resistant HNBR outer cover, it provides excellent resistance to oil-based media while effectively absorbing vibration, reducing pressure surges, compensating for thermal expansion and correcting pipeline misalignmetnt. Designed with a compact 130mm body length configuration, the Teguflex P HO is particularly suited to installations where space is limited while maintaining reliable performance in demanding industrial environments. The unit is available with a variety of flange materials including zinc plated carbon steel and stainless steel, with optional PTFE liners, vacuum rings, flameguards and safety shields available for enhanced operational protection. Approved for ATEX environments and carrying both DNV and ABS approvals, the Teguflex P HO offers a dependable solution for compact oil and gas piping systems operating between -25°C and 120°C.
