    The Patented Baier™ Manway

    The Baier™ Single-Bolt Manway has a unique solution for sealing the tank car manway.  The patented Baier™ system is fundamentally different from all other designs.  Our patented single ram-bolt and strongback design centrally applies force which distributes equally around the cover. There are no troublesome eye-bolts, no unequal loading.  The operator can create a perfect seal in one quick operation with simple hand tools. No re-torqueing is needed. No special sockets or tools.

    The Baier™ O-Ring Sealing System

    The real secret to the success of the Baier™ manway lies in our patented O-ring sealing system: instead of squeezing a flat gasket to achieve a seal, it uses an O-ring positioned between the nozzle wall and the cover sheer ring. This creates consistently uniform compression on the seal. Additional pressure from within only works to the advantage of the system, actually enhancing the sealing force. No other system can make this claim.

    Baier™ specifies our Teflon-encapsulated O-ring, which can last thru a large number of operational cycles, saving replacement and stocking costs.  The gasket material itself is highly resistant to a broad range of chemicals, so that in most cases, only one model will be required.
