APG stocks the V3X79, a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 79 mm (3.11 in), a cross section of 3 mm (0.118 in), and an outside diameter of 85 mm (3.35 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
This material stands up to aggressive chemicals, petroleum oils and fuels, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is specified for excellent resistance to compression set and permeation, very low compression set at elevated temperature. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C).
It sees regular use in aerospace, oil and gas, and automotive fuel systems.
V3X79 ships individually. Unit weight is approximately 3.3545 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
