Gasket
RCF Technologies
Customized gaskets designed to meet specific customer needs are an integral part of RCF’s expertise. These include shim gaskets and single-fastener fire wall plumbing.
Our shim gasket offers solutions to applications with narrow gaps, high pressures, many bolt holes, or any other situation causing extrusion or blow out for gaskets. Rishon® may be used to replace brittle materials such as graphite and graphoil, as well as high temperature materials like asbestos. By using a 1–10 mm shim faced with a single ply of Rishon brand material on either side, no extrusion or blow out is possible. In effect, it has the strength of a metal gasket but the sealing properties of rubber.
Another specialty gasket offered by RCF is our single-fastener gasket used for plumbing firewalls. The overlapped split gives the user a completely fireproof seal while allowing easy access to the wire bundles or tubes being used. Single-fastener access minimizes not only weight, but also reduces installation and removal labor by more than half.

Seals
RCF Technologies
RCF 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 .027 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 .050 inches.
Electrical conductivity/non–conductivity. 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.

Couplings
RCF Technologies
At RCF Technologies, we specialize in lightweight, high-performance couplings made from metal. The advantages of using RCF Technologies products include:
Easy installation. Each coupling can be installed without tools. Clients can choose between snap ring closures and straight sleeve couplings
More flexibility. Each coupling offers a 5° misalignment capability per side, which is greater than the 3° standard in the industry.
More material options. Customers can choose between aluminum, 17-7 stainless steel, and titanium couplings. Couplings can also have customized sizes, lengths, latch types, and configurations.
Simple design. Each coupling has two end caps, two seals, two split rings, and the housing, providing a full assembly.
RCF Technologies also owns Rishon®, a material that can create an FAA-approved fire barrier with a .027” thickness, heat and flame insulation as thin as .050”, and reliable performance at temperatures ranging from -170° F to +850° F.
Our couplings require no tools for installation or removal and are available in high-pressure, snap ring closure, and straight sleeve coupling variants upon request. We also provide customization capabilities for the coupling’s housing length and configuration, diameter, and latch type. These options allow our customers to tailor their couplings to their unique needs.
