Seal design is an important factor in food, dairy, beverage and pharmaceutical processing. An o-ring is a very important part of that design. O-rings are generally installed in a seal to prevent leaking, or loss of fluid. Rubber Fab offers AS568 Standard o-rings, metric, DIN and custom sizes in a wide variety of materials.
There are many factors to consider when choosing an elastomer for your application. O-rings and gaskets are FDA Compliant for use in food applications and Class VI tested for pharmaceutical applications. Rubber Fab Detectomer® products meet and exceed the standards set by the Food Safety Modernization Act. They are detectable by in-line x-ray inspection and metal detection systems, as well as, magnetic separators, therefore reducing costly product loss and recalls.
Quad rings are a unique o-ring with a unique profile, doubling the sealing surface of a traditional o-ring. This design also provides lower friction and because it has more of a square profile, and can resist spiral twisting.
Chemical attack and swelling are the primary causes of o-ring failure. Encapsulated o-rings match the chemical and temperature resistance of solid PTFE o-rings, and possess properties of elasticity and recovery, which are crucial in many sealing applications. Encapsulated o-rings are virtually chemically inert and provide easy cleanup of viscous materials.
