Flange Gasket Design

Flange Gaskets

We have tooling on hand for cutting from 1/2″ to 48″ and pressure rated material in 150#, 300# and 600# for ring or full face flange gaskets. Both ring gaskets and full face gaskets come in metric and standard sizes and in various thicknesses. Materials will vary according to the application with compressed non-asbestos being the standard. Typical flange gasket applications include: HVAC petrochemical, oil and gas, pipelines, plumbing, electronic, chemical, medical, and food processing. Custom Gasket Mfg. makes use of high speed die cutting equipment to produce flange gaskets to your exact requirements. We can supply your flange gaskets with or without pressure sensitive adhesive (PSA) backing.
