1.5MM CS X 19.5MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A measuring an inside diameter of 19.5 mm (0.768 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 22.5 mm (0.89 in), catalogued under part number V1.5X19.5. It compresses into its gland to block fluid or gas migration across a joint. Source specification: Metric O-RING, JIS S20.

This material stands up to aggressive chemicals, aromatic hydrocarbons, and many acids. That behavior comes from the compound itself: Viton® (FKM) is specified for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with amines or low-molecular-weight organic acids.

Typical settings include semiconductor equipment, aerospace, and automotive fuel systems.
