Gasket for a coupler upon a rail car, tank trailer, or related means

摘要

A pipe coupler interconnects pipes and fittings and sections of pipe end to end for transferring bulk dry and fluid materials. The coupler connects various pipe ends, grooved, smooth, and ground, together. The coupler also connects various fittings such as tees and valves to pipe ends. Two arms clamp upon the two pieces of a gasket to seal the connection of pipes and fittings within the coupler. A plurality of ridges upon both surfaces of the piece grasp and seal the end of a pipe. The gasket removes any gaps in the connection that would have trapped material and contaminated later loads of material.
