Silicone Housing Seals

The Superior Alternative to Gaskets

Our silicone housing (face) seals outperform flat gaskets and other gasketing methods for a wide variety of applications. Custom designed to your exact specifications, they feature a round cross-section and are molded to hold superior tolerances to die-cut, flat gaskets. Unlike flat gaskets, the round cross section of silicone housing seals ensures sealing of any potential leak paths.

system pressure in flat gasket vs o-ring housing seal

Flat Gasket

  • Die cut tolerances
  • Large surface contact area
  • High fastener loading required to achieve seal
  • Limited to two-dimensional geometry

O-Ring Housing Seal

  • Molded precision tolerances
  • Point load contact area
  • Lower compressive force required
  • Will better absorb variations in surface flatness

Meeting Your Exact Specifications

Though available in a durometer range of 20-80 Shore A, the silicone housing seal can also be made even softer to match compression set requirements of plastic or metal housing applications. Apple Rubber can produce your seal in the most complex shapes and color-match the silicone material in solid or translucent colors.

Advanced Manufacturing Processes for Cost-Effective Solutions

Apple Rubber's Liquid Silicone Rubber (LSR) systems provide consistent, high-quality and cost-effective housing seals essentially flash-free. We can also utilize the latest compression and transfer molding technologies to meet your requirements.

Fast Prototype and Engineering Assistance

In-house tooling capabilities and an experienced design engineering staff enable Apple Rubber to deliver housing seal prototypes fast. Our engineers have the expertise in polymer technology – with a particular emphasis on silicone and liquid silicone rubber (LSR) – as well as plastics, metals and other materials to assist you in creating the right housing seal solution for your needs.

Wide Range of Standard Colors

Silicone housing seals from Apple Rubber are available in a wide range of colors (solid or translucent) to match application requirements.
