1.5MM CS X 4.5MM ID BLACK FKM 75D

APG stocks the V1.5X4.5, a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 4.5 mm (0.177 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 7.5 mm (0.3 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. This item is further identified as Metric O-RING, JIS S5.

It resists aggressive chemicals, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is known for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where ketones and esters or low-molecular-weight organic acids are present.

You will find this material specified across semiconductor equipment, high-temperature process equipment, and oil and gas.

Stocked as V1.5X4.5 and sold individually. Unit weight is approximately 0.0617 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
