-325 BLACK CHEMOURS VITON 75D O-RING

The VITON75325 is an AS568-325 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 1.475 in (37.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.895 in (48.13 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to many acids, aromatic hydrocarbons, and petroleum oils and fuels. Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving amines or ketones and esters call for a different compound.

Maintenance and OEM teams specify it across aerospace, chemical processing, and oil and gas.
