XP75VIT321 - Quad Ring, Black FKM, Duro: 75, Size: 321 (Min Qty: 3)

Description:

Quad Rings, also known as X-Rings, have a four-lobe design which provides two sealing surfaces, thus requiring less force to maintain an optimal seal, ensuring longevity and less friction. These two contact points create an excellent resistance to leakage, twisting and friction.

Unlike standard o-rings where the parting line is on the surface, on quad rings the parting line is located between the lobes, thus eliminating the common problem of leakage resulting from an irregular parting line.

These quad rings are comprised of FKM, material. This material is a fluoroelastomer derived of fluorocarbon rubber. FKM material provides an excellent resistance to a wide variety of chemicals, weather and compression set requirements and also boasts a good resistance to heat and low gas permeability.

Typical Applications

FKM Quad Rings are suitable for applications with mineral and silicone oils and greases, petrol, diesel and non-flammable hydraulic fuels and aliphatic, aromatic and chlorinated hydrocarbons such as propane and benzene. They are compatible within high-vacuum environments, exposure to ozone and weathering.

Do Not Use With:

FKM Quad Rings are not to be used in applications with ammonia has, alkalis or amines, super-heated steam, glycol-based brake fluids or any low molecular organic acids.
