Zoro Select Viton O-Ring Dash 013 Pack

This pack contains 25 black Viton O-rings with a square profile and dash number 013. They are made for static sealing in automotive and industrial fluid systems. The material resists oils, fuels and many chemicals across a wide temperature range.

Square Profile and Metal Detectable Design

The rectangular cross section seats differently from round O-rings, filling gland corners more completely. Each ring is metal detectable for safety inspection but not X-ray detectable. This helps quality control lines identify contamination without additional scanning equipment.

Temperature Range and Dimensional Limits

The Viton compound handles continuous service from -15 to 400 degrees F with a medium-hard 75A durometer. Actual inside diameter is .4 in, width .07 in and outside diameter .566 in. The square profile limits stretch compared to round sections, so gland design must match these exact dimensions.

Questions about this item

How often will the Viton O-rings with 75A durometer need replacement in continuous service?

Replacement interval depends on the specific application, media, and operating conditions; Viton material rated to 400 degrees F generally provides long service life in compatible fluids.

What is the first limitation when these square-profile rings are used at sustained high temperature?

The temperature range tops out at 400 degrees F; above that the material can degrade and lose sealing performance.

How much heat do the 0.07 in wide rings generate when installed in a dynamic seal running all day?

These are static sealing components; they do not generate heat themselves but will experience the system temperature up to 400 degrees F.
