Air and Water-Tight Self-Sealing Washers

Announcing Self-Sealing Washers to this Growing Family of Reusable, Self-Sealing Fastener Assembly Hardware

These standard, self-sealing washers feature a silicone rubber section bonded to a specially-formed stainless-steel washer.  Pressure range exceeds 100 PSI internal/external, and is UL recognized for NEMA 4x type 6 ratings with an IP 66/68 rating.  Other sealing materials and sizes, including metric, are available for specific applications.  Temperature range of -160°F to +500°F.

Each is designed for use with standard screws, bolts, and lock-nuts to seal panels, casings, housings, and other electrical and non-electrical assembled enclosures, including large fastener clearance holes/slots.  Upon tightening, they provide a 360° seal under the head of a standard screw, bolt, or nut, as well as sealing around the periphery of the washer face, preventing leakage.  In addition, their rubber surface serves to increase the fasteners’ ability to prevent loosening due to vibration.  Typical air and water-tight applications include food and other processing systems, instrumentation, communications, military, heavy-duty vehicles, medical and various industrial types of equipment.  NEMA and other electrical enclosures are also protected.

Washers are available with outside diameters of ½”, 1″, and 1½” for screws/bolts having thread sizes from #6 through ½”.  Lock-nuts can also be used to secure washers.
