Zoro Select Viton O-Ring Pack

This pack contains twenty-five brown Viton O-rings with a nominal inside diameter of 1 3/4 in and a nominal width of 1/16 in. They are rated for a temperature range of -15 to 400 degrees F and have a durometer hardness of 75A. The actual inside diameter measures 1.7 in and the actual width is .07 in. The dash number is 031.

Viton Temperature and Chemical Limits

Viton handles continuous heat up to 400 degrees F and resists many oils, fuels and solvents better than standard nitrile rubber. It is not X-ray detectable and carries a California Proposition 65 warning for reproductive-harm chemicals. The material is not FDA compliant, so it cannot be used in food or pharmaceutical contact applications. Metal-detectable construction helps with contamination control in processing lines.

Check Groove Dimensions Before Ordering

Verify that your gland groove matches the actual inside diameter of 1.7 in and the actual cross-section width of .07 in. Confirm the dash number 031 corresponds to your hardware specification. Ensure the operating temperature stays within the -15 to 400 degrees F range and that the media are compatible with Viton. The brown colour identifies the material but does not indicate a different size.

Questions about this item

Should I choose the PK25 pack or buy individual rings for my 1-3/4 in Viton application?

The PK25 pack supplies twenty-five brown Viton O-rings with a 1.7 in inside diameter and 0.07 in width, giving a ready stock for repeated maintenance on the same groove size.

What does the 400 Degrees F temperature rating mean once the ring is installed in a real machine?

The Viton material remains stable from -15 to 400 Degrees F, so the seal will not soften or crack in hot oil, fuel or hydraulic circuits that reach the upper limit.

How does the Dash 031 standard cap the groove dimensions I can use?

Dash 031 fixes the nominal cross-section at 1/16 in and the inside diameter at 1-3/4 in, so the groove must match 1.7 in ID and 0.07 in width for proper compression.
