Custom Gasket Supplier: Material Selection, Dimensions and Quote Requirements

Quick Answer: CORASEALS is a custom gasket supplier that provides custom cut gaskets, rubber gaskets, PTFE gaskets, graphite gaskets, non-asbestos gaskets, and metal flange gaskets. We quote from drawings, samples, or measured dimensions. Send the material, ID × OD × thickness, operating temperature, pressure, fluid, flange standard, and quantity to get a custom gasket quote.

CORASEALS is a custom gasket supplier that supports pipe flanges, pump casings, valve covers, heat exchangers, sanitary connections, gearboxes, and general industrial sealing. The gasket range includes rubber gaskets, flange gaskets, spiral wound gaskets, RTJ gaskets, kammprofile gaskets, graphite gaskets, PTFE gaskets, non-asbestos gaskets, sanitary gaskets, heat exchanger gaskets, and custom cut gaskets. Every custom gasket order starts with the application data and a drawing, sample, or clear dimensional list.

Gasket selection is not only a material decision. A reliable custom gasket supplier needs to know the flange type, bolt load, surface finish, operating temperature, pressure, and chemical exposure. A material that works in cold water may fail in hot hydraulic oil. A gasket that seals a flat flange may not work on a raised face flange with limited bolt load. CORASEALS asks for the full service condition before recommending a gasket material or cross section.

What a Custom Gasket Supplier Should Ask Before Quoting

To prepare a quote, send the following information:

• Gasket material or service fluid
• ID × OD × thickness or flange standard and nominal size
• Bolt circle, number of bolts, and flange pressure rating if the gasket is for a flanged joint
• Operating temperature and pressure
• Medium or chemical exposure
• Drawing, sketch, sample photo, or physical sample
• Required quantity

For standard flange gaskets, also provide the flange standard and pressure class. For heat exchanger gaskets, provide the manufacturer plate number or a drawing. For sanitary gaskets, provide the connection type, such as tri-clamp, DIN 11851, SMS, or RJT. Do not send only a part code if the profile is unknown. Different manufacturers may use the same code for different dimensions.

Custom Gasket Material Selection

CORASEALS can help match the gasket material to the fluid, temperature, and flange load. The table below shows common service conditions. Temperature limits depend on the specific grade, hardness, filler, and operating environment. Do not select a gasket material by temperature alone.
