HEYClean™ Liquid Tight Threaded Vent Plugs

Heyco HEYClean™ Liquid Tight Threaded Vent Plugs are IP65, IP67, and IP68 rated and feature an integral sealing ring for a superior seal at the mounting hole. HEYClean Liquid Tight Threaded Vent Plugs allow the passage of air for pressure equalization while preventing moisture intrusion, remaining liquid tight. A pressure-compensating seal prevents the buildup of pressure inside electronic enclosures caused by environmental temperature cycling. These Heyco plugs are UL rated for Type NEMA 3R, 4, and 4X applications and represent a cost-effective alternative to metal or steel plugs.
