Sealing bolts

What are Sealing Bolts?

Sealing fasteners are highly specialty fasteners that include sealing bolts, nuts, sealing screws, and washers. Unlike ordinary fasteners, sealing fasteners are designed with a rubber O-ring (or a rubber element) that when squeezed, permanently seals out contaminants. Sealing Fasteners protect against harsh climates as well moisture and gas by preventing contaminants including dirt and water, or any debris or chemicals that can damage or destroy equipment from entering the application through gaps between the fastener and the contact surface. This is achieved through the use of a rubber O ring under the fastener which forms a seal.
