4MM CS X 285MM ID BLACK FKM 75D

Part number V4X285 is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 285 mm (11.22 in), a cross section of 4 mm (0.157 in), and an outside diameter of 293 mm (11.54 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists petroleum oils and fuels, aromatic hydrocarbons, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers excellent resistance to compression set and permeation, 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 hot water and steam or low-molecular-weight organic acids call for a different compound.

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

V4X285 ships individually. Unit weight is approximately 20.423 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
