3.5MM CS X 42MM ID BLACK FKM 75D

Ordered as V3.5X42, this is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 42 mm (1.654 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 49 mm (1.93 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Viton® (FKM) is known for very low compression set at elevated temperature and outstanding high-temperature capability. The material holds up against petroleum oils and fuels, engine and transmission fluids, and aromatic hydrocarbons. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

Typical settings include aerospace, semiconductor equipment, and chemical processing.

This item is sold individually under part number V3.5X42. Unit weight is approximately 2.5083 g. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
