APG stocks the V75MD330, an AS568-330 blue Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 2.1 in (53.34 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.52 in (64.01 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Expect good resistance to aromatic hydrocarbons, engine and transmission fluids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is known for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. The material carries a published service range of -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.
This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. It sees regular use in oil and gas, aerospace, and high-temperature process equipment.
V75MD330 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
