reusable self-sealing washers

AIR & WATER-TIGHT SELF-SEALING WASHERS
APM HEXSEAL announced the addition of SEELOC® self-sealing washers to its 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. SEELOC 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 and bolts 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 or bolt, 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 processing systems, instrumentation, communications, military, heavy-duty vehicles, medical and various industrial types of equipment. NEMA and other electrical enclosures are also protected.Hinge Sketch

SEELOC washers are available with outside diameters of 1/2", 1" and 1 1/2" for screws/bolts having thread sizes from #6 through 1/2".
