Aflas (TFE/P) Seal Ring is a copolymer of tetrafluoroethylene and propylene with a fluorine content of approximately 54%. It is unique due to its resistance against petroleum, steam, phosphate esters and brake fluid. TFE/P also provides improved chemical resistance to a wide spectrum of automotive fluids and additives.

Carboxylated Nitrile (XNBR) is a special type of nitrile polymer that exhibits enhanced tear and abrasion resistance. For this reason, XNBR based materials are often specified for dynamic applications such as rod seals and rod wipers. Heat resistance. • Up to 100°C (212°F) with shorter life @ 121°C (250°F).

FKM or Viton® O-Rings. Made up of a synthetic rubber called fluoroelastomer, Viton® o-rings are a type of sealing component. They come in a variety of FKM types and formulations and offer exceptional resistance to heat, chemicals, oils, and fuels. This makes them suitable for use in a wide range of industries.

FEP [Fluorinated ethylene-propylene] is a thermoplastic material with properties similar to PTFE. O-rings which are seamlessly coated with FEP have an elastic core made from FPM or VMQ and are used if very high thermal or chem¬ical loads are present.

FLUOROSILICONE ( FVMQ ) SEAL RING Fluorosilicone is a hybrid of silicone and fluoroelastomers. More specifically, it combines trifluoropropyl, methyl, vinyl, and silicone. Fluorosilicone O-rings are similar in regards to their mechanical properties to silicone O-rings. However, they have a higher resistance to jet fuel and mineral oils.

HYDROGENATED NITRILE ( HNBR ) SEAL RINGS
HNBR, or hydrogenated NBR, is created by modifying the properties of NBR to increase the materials resistance to ozone, many chemicals, heat, aging, and abrasion. Like NBR, HNBR still holds onto its resistance to oils and fuels.

Nitrile Buna-N (NBR) o-rings are one of the most common and widely used sealing materials because of its excellent sealing and mechanical properties at a low cost. Nitrile offers excellent tensile strength, abrasion resistance, tear resistance, and compression resistance. Optimal environments include petroleum oils and fuels, silicone oils and greases, propane, ethylene glycol, butane, vegetable, mineral oils and greases, dilute acids, and water and steam applications (below 212°F).

Polyacrylate (ACM) o-rings are copolymers of ethyl or butyl acrylate with a combination of chlorine, acid, amide or epoxy compounds. Optimal environments include engines and transmissions with good resistance to petroleum fuels and oils, automatic transmission fluid, type A power steering fluid. Good resistance to mineral oil, sunlight, oxygen, and ozone. ACM stands for Polyacrylate rubber, which is a type of synthetic rubber known for its good resistance to heat, ozone, and weathering. It is made from a copolymer of ethyl/butyl and acrylate, with a combination of chlorine, acid, amide, or epoxy compounds.

Polyurethane rubber is a thermoplastic elastomer formed by reacting a polyol with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Polyurethane rubber is widely used due to its high strength, and excellent tear and abrasion resistance. Polyurethane also provides excellent permeation resistance. Urethane, polyurethane (AU) o-rings are produced by the poly addition reaction of a polyisocyanate with a polyol in the presence of a catalyst. AU has excellent wear resistance, high tensile strength, tear strength, extrusion resistance and elasticity in comparison with any other material.

VMQ (Silicones) are a group of elastomeric materials made from silicone, oxygen, hydrogen, and carbon. Extreme temperature range and low temperature flexibility are characteristics of silicone compounds. As a group, silicones have poor tensile strength, tear resistance, and abrasion resistance.
