-133 BROWN FKM 75D O-RING

APG stocks the VB75133, an AS568-133 brown Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 1.799 in (45.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.005 in (50.93 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to many acids, chlorinated solvents, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) delivers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or hot water and steam are present.

It sees regular use in aerospace, high-temperature process equipment, and oil and gas.

VB75133 ships individually. Unit weight is approximately 1.673 g and nominal inside diameter is listed as 1 13/16 inch. 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.
