Frequently Asked Questions

What is the APPROVED VENDOR Z8525 flat washer used for?

The APPROVED VENDOR Z8525 flat washer seals around 1/4 in screw fasteners to prevent fluid or air leaks. Its neoprene seal provides vibration dampening and corrosion resistance in industrial piping, HVAC, and general maintenance applications where a non-FDA, non-metal-detectable seal is acceptable.

What are the specifications of the APPROVED VENDOR Z8525 flat washer?

The Z8525 is a 1/4 in screw-size flat washer with a 0.281 in inside diameter and a 3/4 in outside diameter. It has a black neoprene seal, is not FDA approved, and is not metal detectable. Supplied in a 25-pack by APPROVED VENDOR, it uses inch-system measurements.

How to install the APPROVED VENDOR Z8525 sealing washer?
