-129 BLUE FKM 75D O-RING

APG stocks the V75MD129, an AS568-129 blue Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 1.549 in (39.34 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.755 in (44.58 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Viton® (FKM) is valued for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The compound resists petroleum oils and fuels, many acids, and engine and transmission fluids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).

The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and oil and gas.

Stocked as V75MD129 and sold individually. Nominal inside diameter is listed as 1 9/16 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
