Viton O-Ring Dash 123 Pack of 10

These square-profile Viton O-rings suit maintenance teams and repair shops that need reliable static seals in high-temperature fluid systems. The FKM material resists oils, fuels and many chemicals across a wide temperature range.

Practical limits of the Viton material

Continuous service is rated from minus 15 degrees to 400 degrees Fahrenheit with a medium-hard 75A durometer. The rectangular cross section measures 0.103 inches wide and the actual inside diameter is 1.1 inches, so the seal fits only glands machined to Dash 123 dimensions.

Build quality and daily implications

Each ring is black, FDA approved and metal detectable but not X-ray detectable, helping quality-control checks in food or pharmaceutical lines. The pack contains ten pieces, giving enough spares for repeated teardowns without reordering.

Questions about this item

Which pack size should I choose for my maintenance kit?

The product is sold as a pack of 10 Viton O-rings, giving you ten identical seals for repeated use or spares.

What does the dash 123 size mean when the ring is installed?

The O-ring has an actual inside diameter of 1.1 in, an actual width of .103 in and an actual outside diameter of 1.38 in, matching the dash-123 groove dimensions.

How does the rectangular cross-section affect the seal in a standard gland?

The rectangular profile provides a wider contact surface than a round cord, improving sealing stability in the groove while the Viton material handles temperatures from -15 to 400 degrees F.
