-277 BROWN FKM 75D O-RING

VB75277 is an AS568-277 brown Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 11.484 in (291.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.762 in (298.75 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists chlorinated solvents, petroleum oils and fuels, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers outstanding high-temperature capability, excellent resistance to compression set and permeation. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or low-molecular-weight organic acids.

Common environments for this compound include aerospace, oil and gas, and automotive fuel systems.

VB75277 ships individually. Unit weight is approximately 19.45 g and nominal inside diameter is listed as 11 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need?
