Frequently Asked Questions

What is the APPROVED VENDOR flat washer used for?

This fiber sealing washer is used to create a leak-resistant seal under the head of an M12 screw or bolt. It is commonly applied in plumbing, pneumatic, and general industrial fastening where a non-metallic, non-FDA-grade seal is acceptable.

The APPROVED VENDOR flat washer Z8648 is a metric M12 fiber seal with a 13 mm inside diameter, 24 mm outside diameter, and 2.5 mm maximum thickness. It is red, not FDA approved, and not metal detectable. Supplied as a 5-pack.

How to select the correct fiber sealing washer size?
