3MM CS X 73MM ID BLACK FKM 75D

APG stocks the V3X73, a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 73 mm (2.874 in), a cross section of 3 mm (0.118 in), and an outside diameter of 79 mm (3.11 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists many acids, petroleum oils and fuels, and aggressive chemicals. Viton® (FKM) is known for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

You will find this material specified across oil and gas, aerospace, and semiconductor equipment.

Stocked as V3X73 and sold individually. Unit weight is approximately 3.1147 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
