-043 BLACK FKM 75D O-RING

APG stocks the V70043, an AS568-043 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 3.489 in (88.62 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.629 in (92.18 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to aromatic hydrocarbons, engine and transmission fluids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is known for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving ketones and esters or low-molecular-weight organic acids call for a different compound.

Common environments for this compound include aerospace, oil and gas, and chemical processing.

Order part number V70043, sold individually. Unit weight is approximately 1.3228 g and nominal inside diameter is listed as 3 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
