Highly resistant to many chemicals, and outstanding resistance to high temperatures. Primarily used where resistance to hot, dry conditions is required. Tolerant to temperature extremes, and resists degradation by fuel and oils. Useful in applications requiring an air-tight seal.īetter resistance to chemicals and high temperatures than most other elastomers.Įxcellent tolerance for temperature extremes, and high resistance to compression set. Resists both weathering and exposure to petroleum oils.Įxtremely low gas permeability resists a diverse range of chemicals. Nitrile is the most commonly used elastomer for sealing applications, and it is the material of choice for petroleum applications.Ĭompared to nitrile, HNBR has better chemical resistance, better heat resistance, and better resistance to seal extrusion. Highly resistant to abrasion and tearing. Because of the clover design, the X-ring has a lower coefficient of friction and has. If you are unsure which material would be best, ask us-we can help you select the right material for your situation. X-Rings are a torus (donut) shaped seal with a clover shaped cross section. Sigma Seals & Gaskets can build seals from elastomers that tolerate high or low temperatures, high or low pressures, dynamic applications, and corrosive environments. In such situations, the walls should be polished to prolong the life of the seal.įor maximum seal longevity, the seal must be constructed from the correct elastomer for the particular application. In dynamic applications, a seal can also fail by abrasion against the walls of the gland. O-rings manufactured from EPDM exhibit an excellent resistance to weathering and. If the pressure difference is too great, then the seal will extrude into the narrow gap between the walls of the gland, and the seal will fail. EPDM rubber is a terpolymer of ethylene, propylene and diene monomers. They also require less compression to make a seal, so they offer a longer service life. Also known as Quattro Seals and X- rings, these X-profile O-rings have four points of contact for a better seal in dynamic applications than round-profile O- rings. Over time and repeated clean-in-place, sterilization, and handling during equipment cleaning, component parts used in food, beverage and pharmaceutical processing equipment and pipework can degrade.

Rubber Fab presents a full line of metal detectable/x-ray inspectable o-rings and cord. If a pressure differential occurs across the gland, then the seal is compressed against the low-pressure side of the gland. X-Profile Oil-Resistant Buna-N O-Ring Assortments. Detectomer® Protection in a 3A Compound O-Ring. When the components are forced closer together, the seal is compressed against the walls of the gland and creates a plug. During operation, the O-ring or X-ring is seated in a specially shaped groove (gland) at the interface between two rigid components.
