Trelleborg Teguflex W Yellow Flanged Rubber Flexible Connectors
Key Information
Trelleborg Teguflex W Yellow bellows are a heavy-duty moulded rubber expansion joint developed for oil, gas and hydrocarbon handling applications involving water, salt water, mineral oils, vegetable and animal oils, oil aerosols, and hydrocarbon products with less than 50% aromatic content. Manufactured with a fluted Epichlorohydrin (ECO) inner tube, nylon cord reinforcement, and an oil resistant ECO outer cover, it is designed to absorb vibration, reduce pressure surges, compensate for thermal expansion and correct pipeline misalignment in demanding industrial service environments. Particularly suited to tank wagons, tankers and fixed oil transfer systems, the Teguflex W Yellow offers excellent resistance to oil-based media while maintaining reliable flexibility and durability. Available with a variety of flange materials including zinc plated carbon steel and stainless steel, the unit can also be supplied with optional PTFE liners, vacuum rings, flameguards and safety shields for enhanced operational protection. Featuring an extended body design for increased movement capability, DNV approval and ATEX suitability, the Teguflex W Yellow provides a dependable solution for larger bore oil and gas piping systems operating between -25°C and 90°C.
