-228 BLACK FKM 90D O-RING

The V90228 is an AS568-228 black Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 2.234 in (56.74 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.512 in (63.8 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to aromatic hydrocarbons, many acids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or amines.

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

Order part number V90228, sold individually. Unit weight is approximately 0.0034 g and nominal inside diameter is listed as 2 1/4 inch. Review your operating media and conditions against this specification before installation.
