Factors for choosing a gasket material

1) Temperature - possibly the most important factor in choosing a gasket material. When higher temperatures at the gasketed joint need to be sealed, the potential choices are quickly eliminated. If the system operating temperatures approach a gasket materials max. continuous operating temperature threshold, the next best material should be chosen.

2) Chemical compatibility to the media to be sealed against (including flushes and system cleanouts). There are many different fluids and gasses to seal against, and many different choices of gasket materials to seal against them.

3) Pressure at the gasketed joint. The internal pressure of the fluid should be a determining factor in choosing a gasket sealing material. If severe cycling or pressures changes occur frequently, a more robust material may be required.

4) Application - this includes all factors such as the number, grade and size of bolts to create compression and the surface areas of the sealed joint.  For EMI gaskets, this includes the amount of emi and rfi shielding required.

Because pressure and temperature are so closely connected, it is often effective to consider them together by measuring Pressure x Temperature or P x T value. Review the specifications of the gasket material you are considering - if they are both near the max. continuous operating limits of the application, a more robust material should be used.

An important factor to consider in selecting materials for gaskets is that most testing for OEM products is conducted under laboratory conditions. Actual field environments must be considered before a recommendation for materials can be made.  In-House tooling speeds manufacturing of custom gaskets & seals.  Non-Conductive and EMI shielded conductive gaskets will help improve performance.

Sealing Devices makes gaskets from the non-asbestos sheet materials from Garlock and all industry leading gasket material OEM's, and high temperature spiral wound / metal gaskets from Flexitallic.

Gasket Types

Sealing Devices makes several types of gaskets from most all sealing materials including non-metallic/compressed sheet, rubber gaskets, and spiral wound metal gaskets. 

Compressed sheet gaskets / PTFE / Fiber reinforced / Flexible Graphite - good for low to medium pressure applicatons.

Rubber gaskets - excellent for sealing water.

Spiral wound gaskets - ideal for high temperature and high temperature applications.

Metal gaskets - camprofile, metal jacketed, ring joints
