Your source for bonded neoprene washers!
Available by themselves or attached to any screw.

All Neoprene Washers Are Bonded With A Metal Backing.

Bonded neoprene washers (also known as sealing washers and cushioning washers) are a specialty washer designed to create an airtight seal between the bolt or screw and the hard surface. The washer spreads stress and strengthens the joint for a high torque application while the rubber washer cushions the joint against the hard surface.

Bonded neoprene washers are used to prevent leakage, distribute pressure of the bolt or screw and also make a great cushioning agent to help with vibrations.  Applications include aircraft, auto, marine, railroads and railroad equipment, mobile homes, air conditioning, hydroponic structures, outdoor signs and many more.
