Seals

At RCF Technologies, we offer custom-manufactured seals made from our proprietary composite material—Rishon®. Our team created Rishon by combining the properties of fabrics and elastomers into a single material. This unique blending of characteristics affords Rishon users access to material properties separate from either parent material. For example, when used for seals, Rishon allows for broader operational temperature ranges, chemical compatibilities, sound and vibration absorption, heat insulation, and electrical conductivity.

Seals Made of Rishon® Material

Our seals demonstrate a host of unique properties that benefit a wide range of industrial applications, including:

  • Broad operational temperature range. Rishon seals are especially suited to high-temperature applications. The material is fully compatible with operating temperatures ranging from -170°F to +850°F while demonstrating little to no thermal changes. These qualities allow users to maintain operation in extreme environments.
  • Rishon material meets Federal Aviation Administration (FAA) standards for fire barriers in thicknesses as low as .037 inches. Additionally, it fulfills all Advisory Circular 20-135 criteria for up to 15 minutes of direct contact with 2000°F flames.
  • Chemical compatibility. Rishon material maintains its integrity after exposure to a wide array of chemicals, such as diesel, jet fuel, and other fluids typical of aircraft applications.
  • Heat and flame insulation. Rishon seals serve as effective heat and flame insulators in material thicknesses as low as 0.050 inches.
  • Electrical conductivity/nonconductivity. Rishon seals are non-conductive, making them ideal for use in critical aerospace and engine applications. Rishon seals can also be designed to be electrically conductive with almost no additional weight.

Customized Shim Gaskets

In addition to our Rishon seals, we also offer a range of specialty gaskets, including shim gaskets and single-fastener gaskets for firewall plumbing. Plus, every RCF gasket is available with a variety of customization options to meet each customer’s unique needs, such as permanent bonding or removable designs. Other potential features include integrated overlapped splits to create a fireproof seal while maintaining easy access to necessary wires and tubing.

Our gaskets find use in a broad range of applications, such as:

  • Anti-icing
  • Engine seals
  • Plenums
  • Thrust reversers
  • Ducting systems
  • Plumbing firewalls

Our clients integrate our customized gaskets into applications across numerous industries, including aerospace, defense, automotive, marine, and general industrial.
