3MM CS X 134MM ID BLACK FKM 75D

APG stocks the V3X134, a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 134 mm (5.276 in), a cross section of 3 mm (0.118 in), and an outside diameter of 140 mm (5.51 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists chlorinated solvents, 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 and very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to hot water and steam or amines will shorten service life.

Typical settings include aerospace, oil and gas, and high-temperature process equipment.

Stocked as V3X134 and sold individually. Unit weight is approximately 5.77 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
