What Is A Neoprene Washer?

Neoprene washers are a unique combination of steel and rubber that serve a distinct purpose. Neoprene washers are steel washers coated or bonded with neoprene, a specific type of durable rubber used in wet suits, hoses, and in elastomeric roofing membranes.
They are most often seen in plumbing, although these specially formulated washers are also used in the alternative energy industry and with various electronics.

The purpose of these washers in plumbing applications is generally to create a tight fitting seal. The flexibility of rubber means that the bearing surface can be compressed for a tight fit. The neoprene coating also provides effective protection against corrosion, a common problem in these applications.
Neoprene washers are used with polycarbonate panels, most often on roofs and in windows as a replacement for glass. The composition of this washer allows for an effect seal to be created between the panels, around the edges, and on any angled corners.
They are only part of a system that ensures a polycarbonate roof or window is waterproof. But neoprene washers also play an important role in distributing the load of those fasteners that keep the panels together.
Indispensable in many different applications, neoprene washers still live up to the basic purpose of all washers – to provide a flat bearing surface for better load distribution and prevent embedment.
