This o-ring is supplied in brown Viton® (FKM) 75 Shore A built to an inside diameter of 4.5 mm (0.177 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 7.5 mm (0.3 in), catalogued under part number VB75M1.5X4.5. It compresses into its gland to block fluid or gas migration across a joint. Supplementary detail from the product record: Metric O-RING, JIS S5.

The compound resists engine and transmission fluids, chlorinated solvents, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service.

Maintenance and OEM teams specify it across automotive fuel systems, oil and gas, and semiconductor equipment.
