SEELOC®
Air & water-tight self-sealing washers

SEELOC® Washers are self-sealing, vibration-resistant washers, each having a silicone rubber section, molded and bonded to a stainless steel formed washer. These washers are designed for use with regular screws, bolts, or studs for sealing panels and enclosures having standard as well as large clearance holes or adjustment slots, and can also be used to seal openings of protrusions. Upon tightening, a seal is formed under the head of the fastener as well as around the periphery of the washer face.
