Heyco HEYClean™ Liquid Tight Snap-In Vent Plugs

Heyco HEYClean™ Liquid Tight Snap-In Vent Plugs feature an integral sealing ring for a superior seal at the mounting hole location. These vent plugs allow the passage of air for ventilation and heat dissipation, prevent moisture intrusion, and remain liquid-tight. The snap-in vent plugs consist of a filter membrane, which is both hydrophobic and oleophobic, and prevents moisture and particulate contamination in electronic enclosures. These vent plugs pressure-compensating seals prevent the buildup of pressure inside electronic enclosures due to environmental temperature cycling. The snap-in vent plugs are IP65, IP67, and IP68 rated, and UL-rated for Type NEMA 3R, 4, and 4X applications. These vent plugs are quick and easy to install into threaded (LTTVP) and clearance (LTSV) holes.
