V3.5X29 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 29 mm (1.142 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 36 mm (1.42 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
It resists aggressive chemicals, many acids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit 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. Verify compatibility before use with hot water and steam or low-molecular-weight organic acids.
Typical settings include oil and gas, high-temperature process equipment, and aerospace.
Order part number V3.5X29, sold individually. Unit weight is approximately 1.7709 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
