  • Viton material withstands -15 to 400°F

Zoro Select Square Profile Viton O-Ring Dash 118

This pack contains ten black Viton O-rings with a square cross-section profile. They are designed for sealing applications requiring resistance to high temperatures and chemical exposure. The nominal inside diameter measures 7/8 inch with an actual inside diameter of 0.8 inch. Each ring has a durometer rating of 75A.

Installation notes and common issues

The rectangular cross-section seats in standard dash 118 grooves without special tools. Care must be taken to avoid twisting the square profile during insertion as this can create leak paths. Lubrication compatible with Viton eases installation and prevents surface damage. Metal detectable properties allow identification in processing lines.

Capacity and operating limits

The material withstands continuous temperatures from -15 to 400 degrees Fahrenheit. Actual width measures 0.103 inch with an outside diameter of 1.068 inches. These rings are not FDA compliant and are not X-ray detectable. They suit industrial fluid and gas sealing where medium hardness and thermal stability are required.

Questions about this item

How can I confirm the square-profile Viton O-ring is sealing correctly after installation?

Verify that the 0.8 in inside diameter and 0.103 in width sit fully in the groove with no visible gaps; the 75A durometer Viton should compress evenly and hold pressure up to 400 °F without extrusion.

What comes in the PK10 pack and are any installation tools or lubricants included?

The pack contains ten black Viton O-rings to dash 118 dimensions; no installation tools, lubricants or additional hardware are supplied.

Which dash-size version should I choose for a groove measuring 0.8 in ID and 0.103 in cross-section?

Select the dash 118 square-profile Viton O-ring — its 0.8 in actual inside diameter and 0.103 in actual width match those groove dimensions.
