SKU CH-8Q4C-D0CRX

Pack of 100 Viton O-rings, 7/16 in inside diameter, rated from -15 to 400 °F and FDA approved

  • Viton material resists chemicals and heat to 400 °F
  • Pack of 100 O-rings covers large maintenance jobs
  • 7/16 in inside diameter fits standard SAE grooves
  • 75A durometer gives firm seal without excessive compression
  • FDA approved material suits food and pharma contact

What It Is

This pack contains one hundred brown Viton O-rings with a nominal inside diameter of 7/16 inch and a nominal width of 1/16 inch. They are designed for static or dynamic sealing in automotive, industrial and fluid-handling systems where chemical resistance and temperature stability are required.

Critical Specification

The O-rings carry a durometer rating of 75A and an operating temperature range from -15 to 400 degrees Fahrenheit. This combination determines whether the seal will maintain elasticity and resist extrusion in your specific pressure and thermal environment.

Thermals And Compliance

Viton material remains stable across the full rated temperature span without hardening or cracking. The seals are FDA approved for food-contact applications and carry a California Proposition 65 warning for reproductive-harm chemicals.

Questions about this item

What does the 7/16 inch inside diameter mean when the O-ring is installed?

The actual inside diameter measures .4 in, so the ring seats on a shaft or bore of that size and the Viton material stretches to seal against the mating surface.

How does the 75A durometer rating affect sealing performance?

A 75A durometer gives a medium-hard feel that resists extrusion in high-pressure fluid systems while still conforming to surface finish variations.

What groove dimensions are needed to fit the 1/16 inch nominal cross section?

The actual cross section is .07 in, so the groove depth and width must be machined to accommodate that thickness and allow proper compression.
