Air & Liquid-Tight Self-Sealing Washers

APM Hexseal presents high-pressure washers that are air and liquid-tight

Image of APM Hexseal's Air & Liquid-Tight Self-Sealing WashersAPM's SEELOC® high-pressure washers are designed to seal out air, water, lubricants, and other liquid and gaseous contaminants from either entering or escaping the equipment. Self-Sealing SEELOC stainless steel washers are vibration resistant and will seal to 100 psi. Easy to use, they work well with conventional screws, bolts and studs for sealing panels and enclosures that may also have large or irregular shaped holes or slots. They can even seal protruded holes/openings. Upon tightening, a seal is formed within the shank and threaded surface of the fastener as well as around the periphery of the silicone rubber bonded face. IP66/68 rated. UL Recognized Component. RoHS and DFARS Compliant. Temperature range of -160°F to +260°F (-106°C to +260°C). Wide choice of metric and standard sizes. Made in USA.
