Die-Cut Gaskets & Industrial Gaskets

Industrial gasket manufacturing experts offer in-house tooling

As a premier North American manufacturer of die-cut gaskets, our 200 pieces of manufacturing equipment and in-house tooling and die-making allow us to make gaskets from commercial and mil-spec rubber, compressed sheet gaskets, cloth inserted gaskets, paper, fabric, felt and most any other material with quick cut options.


Die-cut gaskets seal between two different surfaces under compression. Sealing Devices is an expert manufacturer of die-cut industrial gaskets from all materials.  Die-cut industrial gasket sealing is a result of compressive forces created by sufficient bolt load, and also works to fill the imperfections on the mating surfaces to be sealed.  (ANSI Flange Standards)

Key factors for choosing die-cut industrial gasket materials:

1) Temperature is the most important factor in choosing die-cut industrial gasket materials. When high temperatures at the gasketed joint need to be sealed, the potential choices are quickly eliminated.  If the system operating temperature approaches a die-cut gasket material's maximum continuous operating temperature, the next best material should be chosen.

2) Chemical compatibility to the media. There are many different fluids and gases to seal, and many choices of die-cut industrial gaskets.

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

4) Application and factors such as the number, grade and size of bolts create compression on the surface area of the sealed joint.  For EMI die-cut gaskets, this includes the amount of EMI shielding needed.

5)  Pressure x Temperature are so closely connected, it is often effective to consider them together by measuring Pressure (P) x Temperature (T) value. Review the specifications of the die-cut gasket material you are considering. If they are both near the maximum continuous operating limits, a more robust material should be used.

An important factor to consider in selecting materials for die-cut industrial gaskets is that most testing for OEM products is conducted under laboratory conditions. Actual field environments must be considered before a material recommendation can be made. In-house tooling speeds manufacturing of custom gaskets and seals.
