Q-228 FLUOROELASTOMER 75 Q RING

Ordered as QV70228, this is an AS568-228 black Viton® (FKM) 75 Shore A Quad-Ring supplied with an inside diameter of 2.234 in (56.74 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.512 in (63.8 mm). The quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Viton® (FKM) is known for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. It resists chlorinated solvents, aggressive chemicals, and aromatic hydrocarbons. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or low-molecular-weight organic acids call for a different compound. The profile itself contributes two sealing bands per contact face rather than one and a parting line located away from the sealing surface.

Typical settings include oil and gas, chemical processing, and semiconductor equipment.
