  • Viton material withstands -15 to 400 degrees F

  • Square profile dash 210 fits 0.7 in ID grooves
  • 75A durometer provides medium-hard sealing performance
  • Pack of 10 supplies multiple replacement seals

Square-Profile Viton O-Ring Pack

This pack contains ten square-profile O-rings made from Viton fluoroelastomer with a 75A durometer hardness. Each ring has a nominal inside diameter of 3/4 inch and a nominal width of 1/8 inch, matching Dash 210 dimensions. The seals are black, metal-detectable and operate across a temperature range of -15 to 400 degrees Fahrenheit. They are not FDA compliant and not X-ray detectable.

Sustained High-Temperature Sealing

The Viton material maintains its mechanical properties and chemical resistance during continuous exposure up to 400 degrees Fahrenheit without hardening or cracking. Medium-hard 75A durometer resists extrusion in dynamic or static glands under prolonged pressure cycles. Actual inside and outside diameters of .7 and 1.012 inches ensure consistent compression set performance over the full temperature span. Rectangular cross-section provides a larger sealing footprint than round equivalents.

Compatibility Checks Before Ordering

Verify the gland dimensions match the actual inside diameter of .7 inch and actual width of .139 inch for proper squeeze. Confirm the application does not require FDA-compliant materials, as these rings are not approved for food or pharmaceutical contact. Ensure metal-detectable properties satisfy your quality-control system and that X-ray detection is not required. Check chemical compatibility with the specific fluids present at operating temperatures.

Questions about this item

How does the Viton material hold up to continuous 400-degree heat without degrading?

The Viton O-ring is rated for a temperature range of -15 to 400 degrees F, so it maintains sealing integrity at the upper limit during sustained high-heat operation.

What groove dimensions must my hardware provide for the dash 210 square profile to seal correctly?

The O-ring has an actual inside diameter of .7 in, actual width of .139 in, and actual outside diameter of 1.012 in, requiring a rectangular groove matching those dimensions.

Will the 75A durometer rectangular rings fit the same dash 210 glands as standard round O-rings I already use?

No, the square profile cross-section differs from round O-rings, so existing dash 210 glands must be machined for a rectangular cross-section to seat these rings properly.
