-337 BLACK CHEMOURS VITON 75D O-RING

Ordered as VITON75337, this is an AS568-337 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 2.975 in (75.57 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.395 in (86.23 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against many acids, petroleum oils and fuels, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) delivers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with hot water and steam or low-molecular-weight organic acids.

Maintenance and OEM teams specify it across high-temperature process equipment, oil and gas, and automotive fuel systems.

VITON75337 ships individually. Unit weight is approximately 10.474 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
