APM self-sealing washers

The APM line of self-sealing washers and fasteners are designed to seal out air, water, lubricants and other liquid or gaseous contaminants.

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