SEELOC® self-sealing washers become popular in alternative energy industry

Tuesday, May 31st, 2011


Mounted on a NEMA enclosure, independent of the tower,  or within the turbine nacelle, SEELOC — self-sealing washers are finding new applications  for sealing doors and knockouts. For use wherever environmental internal seepage  is problematic — when a common washer is unable to block contaminants,  such as moisture, dust, sunlight, and ozone.  SEELOC is a natural for green applications.

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  for use with regular screws, bolts or studs for sealing panels and enclosures having large or irregular clearance holes or slots, and can also be used to seal openings of protruded mounting holes.  Self-sealing washers and fasteners are designed to seal out air, water, lubricants and other liquid or gaseous contaminants. Upon tightening, a seal is formed within the shank and threaded surface of the fastener as well as around the periphery of the washer face.
