Manway Gaskets

Gaskets to fit AAR-1, UTC-1, TRN-1 Manways

M Barnwell Services Manway Gaskets incorporates raised sealing features for a more compact seal. During adverse conditions and multiple cycles, the seal will remain tight, reliable and reusable. The single sized gasket will fit the majority of Manways simplifying inventory and selection requirements.

Manway Gaskets are specifically designed to help the installation process and are manufactured from 100% pure PTFE. With easy installation, the Manway Gasket will compress and conform to allow exceptional load retention and will remain tight during excessive vibration. The unique raised sealing features allows the Manway Gasket to perform under the limited bolt load and the precise seating surface nozzle.
