die cut gaskets and industrial kiss cut gaskets

gasket manufacturing experts with in-house tooling

As a premier North American manufacturer and OEM of die cut gaskets, our 200 pieces of manufacturing equipment, and in-house tooling and die making to offer all gaskets from commercial and mil-spec rubber, compressed sheet gaskets, cloth inserted gaskets, paper, fabric, felt with quick cut turn 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.  The die cut industrial gaskets sealing is a result of the compressive forces created by sufficient bolt load, and also works to fill the imperfections on the mating surfaces to be sealed.  (ANSI Flange Standards)die_cut_gaskets

Key factors for choosing die cut industrial gaskets materials:

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

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

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 pressures changes occur frequently, a more robust material may be required.

4) Application - All factors such as the number, grade and size of bolts to create compression and the surface areas of the sealed joint.  For EMI die cut 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 die cut 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 die cut industrial 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 Garlock non-asbestos sheet materials and other gasket material OEM's, and specialize in high temperature spiral wound and metal gaskets from Flexitallic. 

Gasket Types

Sealing Devices offers several types of gaskets from high temperature and low temperature sealing materials including non-metallic/compressed sheet, rubber, 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

We also offer specialized die cut gasket materials including: Garlock Blue-Gard Style 3000, Garlock Style 3400, Garlock Style 3700, Garlock Gylon Style 3540, Garlock Gylon Style 3510, Garlock Style 3545, Garlock Style 706, Multi-Swell style.  Also Bendix head and flange gaskets.

Call us at 800-727-3257 to determine the compressed sheet gasketing material for your next gasket sealing project. 


Offering Klinger C-4300 for high temperature gasket rating, and C-4401 for excellent sealability and chemical resistance.
