This quad-ring is supplied in AS568-127 black Viton® (FKM) 75 Shore A quad profile with an inside diameter of 1.424 in (36.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.63 in (41.4 mm), catalogued under part number VQ4127. It uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.
Expect good resistance to chlorinated solvents, engine and transmission fluids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. 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 amines.
You will find this material specified across oil and gas, high-temperature process equipment, and automotive fuel systems.
Order part number VQ4127, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
