Zoro Select Viton O-Ring 13 mm ID

This pack contains twenty-five black Viton O-rings with a 13 mm inside diameter and 2.5 mm cross-section. They are rated for temperatures from -15 to 400 degrees F and carry FDA approval. The 75A durometer gives a medium-hard feel suitable for demanding sealing tasks. Metric sizing ensures compatibility with standard hardware.

Suits fuel and oil systems needing chemical

These rings handle aggressive fluids and high heat where standard nitrile would fail. They are not X-ray detectable, so they do not suit production lines that mandate X-ray inspection. Buyers who need metal-detectable seals for food-safety compliance should look elsewhere. The dash number is not applicable for Mil-Spec ordering.

75A durometer Viton rated to 400 degrees F

The 75A hardness and 400-degree upper limit decide whether this material survives your media and temperature. Softer or lower-rated compounds will extrude or degrade in the same service. Verify that the 13 mm ID and 2.5 mm width match your groove dimensions before ordering.

Questions about this item

What groove width do I need in my existing hardware for the 2.5 mm cross-section?

Machine a groove 2.5 mm wide so the round cross-section seats without stretch or pinch.

Will the 75 A durometer feel too stiff beside the softer rubber seals I already use?

Medium-hard 75 A Viton resists extrusion better than softer rubber, so it stays seated under pressure.

How can I confirm the seal is working after installation?

Pressurise the system to its normal operating level; no fluid or gas should escape past the 13 mm inside diameter.
