die cut gaskets and 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

Die cut Gaskets seal between two different surfaces, under compression, and Sealing Devices is an expert manufacturer of die cut industrial gaskets from all materials.  Die cut industrial gaskets 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 gaskets materials:

1) Temperature - 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 temperatures approach a die cut gasket material's max continuous operating temperature, the next best material should be chosen.

2) Chemical compatibility to the media to be sealed (including system cleanouts). 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 pressures changes occur frequently, a more robust material may be required.

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

5)  P x T - 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, 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.   Watch a brief video on our die-cutting gasket capabilities.

Sealing Devices makes Garlock non-asbestos gaskets from sheet materials, and specialize in high temperature spiral wound and metal gaskets from Flexitallic. 

Gasket Types

We offer several types of gaskets for high temperature and low temperature applications, 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 applications.

Rubber gaskets - excellent for sealing water.

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

Metal gaskets - Camprofile, metal jacketed, ring joints, and spiral wounds.

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.
