Ordered as V4X32, this is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 32 mm (1.26 in), a cross section of 4 mm (0.157 in), and an outside diameter of 40 mm (1.57 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
The compound resists petroleum oils and fuels, aggressive chemicals, and engine and transmission fluids. Viton® (FKM) offers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with amines or low-molecular-weight organic acids.
Maintenance and OEM teams specify it across aerospace, oil and gas, and chemical processing.
Stocked as V4X32 and sold individually. Unit weight is approximately 2.669 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
