VB75M2.5X13 is a brown Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 13 mm (0.512 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 18 mm (0.71 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
This material stands up to many acids, 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. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or amines are present.
You will find this material specified across high-temperature process equipment, oil and gas, and aerospace.
This item is sold individually under part number VB75M2.5X13. Unit weight is approximately 0.4955 g. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
