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.

O-Ring Sizing Cones

O-Ring measurement cones are the ideal tool for quick and easy identification of standard AS568 O-Ring sizes. The base of the cone has 5 slots to determine the o-ring width. Just slide the o-ring over the cone to identify the corresponding dash #. Dash Numbers are permanently molded into steps around the cone for precise identification. Cones are in stock and available for purchase.

Detectomer® Detectable/X-Ray Inspectable O-rings

X-ray and metal detection systems provide confidence to food, dairy and pharmaceutical manufacturers by insuring product safety and integrity as outlined by the Food Safety Modernization Act. Developing an effective inspection program to detect contaminants and to monitor the consistency and quality of product helps avoid product waste, recalls, costly down time and customer complaints. State of the art metal detection and x-ray inspection systems help ensure product and package integrity by identifying contaminants, scanning for missing or broken products, detecting packing voids, confirming fill levels and controlling product and package mass and fat analysis. The entire Detectomer® family of products can be detected in use with packaging and product that includes glass, metal, stone, and high-density plastics, even for products packaged in foil or metalized film.

*Note: Silicone Metal Detectable/X-ray Inspectable O-Rings have a temperature range of -70°F to 390°F.
