TUFF-RAIL® Manway Gaskets

Garlock TUFF-RAIL Manway Gasket

The GYLON® TUFF-RAIL® Family consists of two tank car manway gaskets, GYLON® 3545 & 3504 TUFF-RAIL®. The TUFF-RAIL ® patent pending technology incorporates raised sealing features for a tighter seal in less than ideal bolting conditions, even after multiple cycles. Engineered to a single size, these gaskets fit the most common manways (AAR-1, UTC-1, TRN-1) simplifying gasket selection and inventory requirements. Constructed from our industry proven GYLON® material, TUFF-RAIL ® manway gaskets have been tested for reliability, reusability, and superior performance over other similar PTFE materials.
