SKU CH-M7HK-11HA8

Viton O-ring pack of 25 seals with 13/16 in inside diameter and 1/8 in width for temperatures from -15 to 400 degrees F

  • Viton material resists chemicals and heat to 400 °F
  • Medium-hard 75A durometer balances seal strength with easy installation
  • FDA-approved compound suits food and pharmaceutical contact
  • Precise 0.7 in ID and 0.139 in width ensure reliable fit
  • Pack of 25 reduces reorder frequency for maintenance teams

Precision Sealing for Demanding Fluids

These Viton O-rings suit technicians maintaining hydraulic or fuel systems that see aggressive chemicals and wide temperature swings. The pack of twenty-five brown rings covers repeated service intervals or small production runs without needing to reorder. Each ring carries FDA approval for incidental food contact where required.

Consistent Compression Through Thermal Cycles

The 75A durometer compound resists permanent set when the system moves between minus fifteen and four hundred degrees Fahrenheit. Actual inside diameter of point seven inches and cross-section of point one three nine inches stay stable under sustained pressure, preventing the slow leak paths that softer materials develop over time.

Heat-Resistant Viton Limits Hardening and Weep

Brown Viton retains elasticity at the upper end of the rated range, so fittings stay sealed during extended high-temperature operation. The medium-hard rating balances extrusion resistance with low closure force, reducing the bolt torque needed for reliable metal-to-metal contact without over-compressing the groove.

Questions about this item

How hot can the Viton O-ring rated to 400 degrees F get during continuous all-day operation?

The Viton material is rated for a temperature range of -15 to 400 degrees F, so it will withstand sustained heat up to that limit.

What groove dimensions must my hardware already have to fit the 13/16 inch inside diameter and 1/8 inch cross-section O-ring?

Your groove must accept a nominal 13/16 inch inside diameter and 1/8 inch width, corresponding to actual dimensions of 0.7 inch ID and 0.139 inch width.

Will the dash 211 Viton O-ring with 75A durometer seal reliably against the older metal flanges I plan to keep?

The medium-hard 75A durometer and 1.074 inch actual outside diameter provide a firm seal on standard dash 211 grooves in existing metal hardware.
