Baier Single Bolt Manway Cover Assembly

The Single-Bolt Manway Cover Assembly is a patented, purpose-built sealing solution engineered for the railway tank car industry, delivering superior performance while helping prevent non-accidental releases. Its centrally applied single ram-bolt and strongback design distributes clamping force evenly around the cover, allowing operators to achieve a uniform, reliable seal in one quick operation using standard hand tools without re-torquing or special equipment. Featuring an advanced O-ring sealing system that uses internal tank pressure to enhance sealing force and a durable, chemically resistant polytetrafluoroethylene encapsulated gasket, this AAR-approved assembly under E152106 provides long-term reliability with reduced maintenance and inventory costs.
