Stahlin REHPSERIES3 Fiberglass Enclosure Hole Plug Kit

Product Description

The STAHLIN REHPSERIES3 is a fiberglass hole plug assembly kit designed to seal unused conduit knockouts in electrical and instrument enclosures. The kit includes HP7 and HP8 plug configurations, providing corrosion-resistant gasketed closure for 2-inch diameter holes accepting 1-inch and 1-1/4-inch conduit. Built from fiberglass, this plug assembly carries UL approval and meets NEMA 4X/6P, IP66, and IP68 ratings. It is installed by licensed electricians and instrument technicians who need a long-lasting, non-metallic sealing solution that holds up in harsh environments without contributing to galvanic corrosion or UV-related degradation.

This kit is suited for use on electrical enclosures and instrument enclosures in industrial, commercial, and utility installations where exposure to moisture, chemicals, or extreme temperatures is a concern. The fiberglass construction provides significantly better UV resistance compared to soft rubber plugs that become brittle over time. It also eliminates galvanic corrosion concerns that arise when dissimilar metals are used together in an enclosure assembly. The REHPSERIES3 is a cost-effective alternative to carbon steel and stainless steel hole plug options.

Compatibility

Designed for use on electrical and instrument enclosures requiring NEMA 4X/6P, IP66, or IP68 rated hole sealing. Compatible with 2-inch diameter knockout holes sized for 1-inch and 1-1/4-inch conduit entries.

Installation Notes

Installation is typically performed by a licensed electrician or instrument technician following applicable NEC requirements. De-energize all circuits and verify enclosure is free of voltage before opening or modifying the enclosure. Ensure the knockout hole is clean and free of burrs before seating the gasketed plug to maintain the NEMA and IP sealing ratings. Do not overtighten or deform the gasket during installation, as this may compromise the watertight seal.
