Stahlin REHPSERIES5 Fiberglass Enclosure Hole Plug Kit

Product Description

The STAHLIN REHPSERIES5 is a fiberglass hole plug assembly kit designed to seal unused conduit openings in electrical and instrument enclosures. It accepts a 2-1/2 inch conduit knockout, fitting a 3.38 inch diameter hole. The gasketed design maintains a watertight, dust-tight seal rated to NEMA 4X/6P and IP66/IP68 standards. This kit includes the HP11 configuration plug and carries UL approval. Fiberglass construction resists corrosion, UV degradation, and galvanic reactions, making it a direct functional improvement over carbon steel, stainless steel, and soft rubber alternatives. Licensed electricians and instrument technicians install this plug when decommissioning or re-routing conduit entries on protected enclosures.

This plug assembly is used on electrical and instrument enclosures where open conduit knockouts must be sealed against moisture, dust, and corrosive environments. It is well suited for industrial, commercial, and utility applications where long-term chemical and UV resistance is required. The NEMA 4X/6P rating covers both indoor and outdoor installations, including locations subject to hosedown, submersion, and harsh chemical exposure. The HP11 configuration is specific to the Series 5 hole plug lineup within the STAHLIN fiberglass enclosure product family.

Key Features

• Fiberglass construction provides superior corrosion resistance compared to carbon steel and other metallic alternatives
• Gasketed seal meets NEMA 4X/6P, IP66, and IP68 ratings for watertight and dust-tight performance
• Resists UV degradation better than soft rubber plugs that become brittle under extreme temperature cycling
• Will not create galvanic corrosion when used with dissimilar metal enclosure hardware
• UL approved for use on electrical and instrument enclosures
• Kit includes HP11 configuration plug; made in the USA

Compatibility

Designed for use on electrical and instrument enclosures with a 2-1/2 inch conduit knockout size and a 3.38 inch diameter hole opening. Maintains chemical resistance consistent with STAHLIN fiberglass enclosure products.

Installation Notes

Installation is typically performed by a licensed electrician or instrumentation technician. De-energize all circuits and follow lockout/tagout procedures before working inside or on any enclosure. Ensure the hole diameter matches the 3.38 inch specification before installing the plug to maintain the NEMA 4X/6P and IP66/IP68 seal integrity. Verify that the gasket seats fully and evenly around the knockout opening upon final assembly.
