APG stocks the V3.5X47.7, a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 47.7 mm (1.878 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 54.7 mm (2.15 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies. This item is further identified as Metric O-RING, JIS P48.

The compound resists many acids, aromatic hydrocarbons, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is valued for outstanding high-temperature capability and very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or hot water and steam.

It sees regular use in oil and gas, high-temperature process equipment, and semiconductor equipment.

This item is sold individually under part number V3.5X47.7. Unit weight is approximately 2.8881 g. Check the compound against your process media, pressure and temperature before committing to a design.
