1/2 Inch Viton O-Rings for Fluid Sealing

This pack contains 25 white Viton O-rings with a nominal inside diameter of 1/2 inch and a nominal cross-section width of 1/16 inch. They are designed for static or dynamic sealing in fluid and lubricant systems. The material meets FDA requirements for incidental food contact. Buyers needing larger diameters or different elastomers will not find a match in this specific pack.

Viton Material Holds Shape Under Continuous Heat

Viton fluorocarbon handles sustained temperatures up to 400 degrees Fahrenheit without permanent deformation. The 60A durometer rating provides medium-hard resilience that resists compression set during long dwell times. It also withstands exposure to oils, fuels and many aggressive chemicals better than standard Buna-N. Applications requiring continuous service above 400 degrees F need a different compound.

Low Friction Surface Reduces Wear and Noise

The smooth white finish lowers breakout friction in reciprocating or rotary motion, helping to prevent stick-slip chatter. Viton's inherent chemical stability means the rings do not swell or soften in common hydraulic fluids, keeping leak paths tight. Power consumption in the sealed system stays consistent because the seal geometry remains stable. Installations needing metal-detectable or X-ray-detectable seals should verify suitability separately.

Questions about this item

Will the Viton O-rings maintain their seal when the system runs continuously at the upper end of the -15 to 400 °F range?

Viton material rated to 400 °F is designed to retain elasticity and sealing force during prolonged high-temperature operation.

What groove dimensions must my existing hardware provide for the 1/2 in nominal ID and 1/16 in cross-section O-rings?

Groove should accommodate 0.4 in actual inside diameter and 0.07 in actual width for proper compression.

Can these dash-014 Viton rings replace older nitrile seals in the same gland without changing the hardware?

Same dash-014 dimensions fit the existing groove; Viton offers higher temperature and chemical resistance than nitrile.
