4MM CS X 105MM ID BLACK FKM 75D

APG stocks the V4X105, a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 105 mm (4.134 in), a cross section of 4 mm (0.157 in), and an outside diameter of 113 mm (4.45 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to aggressive chemicals, many acids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or hot water and steam.

Typical settings include aerospace, chemical processing, and semiconductor equipment.

V4X105 ships individually. Unit weight is approximately 8.012 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
