-025 BROWN FKM 90D O-RING

Part number VB90025 is an AS568-025 brown Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 1.176 in (29.87 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.316 in (33.43 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Viton® (FKM) is widely chosen for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. This material stands up to petroleum oils and fuels, engine and transmission fluids, and many acids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or hot water and steam call for a different compound.

Typical settings include high-temperature process equipment, automotive fuel systems, and chemical processing.

Order part number VB90025, sold individually. Unit weight is approximately 0.5573 g and nominal inside diameter is listed as 1 3/16 inch.
