3MM CS X 10.5MM ID BLACK FKM 75D

The V3X10.5 is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 10.5 mm (0.413 in), a cross section of 3 mm (0.118 in), and an outside diameter of 16.5 mm (0.65 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to many acids, aggressive chemicals, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in ketones and esters or amines.

Maintenance and OEM teams specify it across oil and gas, semiconductor equipment, and high-temperature process equipment.

V3X10.5 ships individually. Unit weight is approximately 0.566 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
