-417 BLUE FKM 75D O-RING

APG stocks the V75MD417, an AS568-417 blue Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 3.475 in (88.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.025 in (102.24 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against petroleum oils and fuels, aromatic hydrocarbons, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. It sees regular use in oil and gas, chemical processing, and semiconductor equipment.

Reference part number V75MD417 when ordering; the item is sold individually. Nominal inside diameter is listed as 3 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
