Stahlin REHPSERIES7 Fiberglass Enclosure Hole Plug Kit

Product Description

The STAHLIN REHPSERIES7 is a fiberglass hole plug assembly kit designed to seal unused conduit openings in electrical and instrument enclosures. It accepts a 3-1/2 inch conduit knockout and fits a 4.5 inch diameter hole. The gasketed design maintains a watertight seal rated to NEMA 4X/6P and IP66/IP68, making it suitable for wet, corrosive, and submersible environments. Fiberglass construction eliminates the galvanic corrosion risk associated with dissimilar metal combinations. The kit includes the HP13 configuration and carries UL approval. Licensed electricians and instrument technicians install this plug when a conduit entry point is no longer needed or was never used.

This plug kit is used on electrical enclosures and instrument enclosures where open knockouts must be sealed to preserve the rated ingress protection of the enclosure. NEMA 4X/6P ratings apply, so it is appropriate for indoor and outdoor installations exposed to washdowns, moisture, and corrosive atmospheres. Fiberglass maintains UV resistance far better than soft rubber plugs, which become brittle under temperature cycling and repeated UV exposure. It also resists the full range of chemical environments where current Stahlin fiberglass products are specified.

Key Features

• Gasketed corrosion-resistant construction maintains NEMA 4X/6P and IP66/IP68 enclosure ratings
• Fiberglass material eliminates galvanic corrosion risk compared to dissimilar metal plugs
• Superior long-term UV resistance versus soft rubber alternatives that become brittle over time
• Fits 4.5 inch diameter hole with 3-1/2 inch conduit knockout size
• UL approved for use on electrical and instrument enclosures
• Manufactured in the USA

Compatibility

Designed for use on electrical and instrument enclosures requiring NEMA 4X/6P or IP66/IP68 rated hole plug sealing at a 3-1/2 inch conduit knockout with a 4.5 inch diameter hole opening.

Installation Notes

Installation is typically performed by a licensed electrician or instrumentation technician. De-energize the enclosure and verify lockout/tagout procedures are in place before opening any enclosure panel. Ensure the hole diameter and conduit knockout size match the plug specifications before installation. Follow applicable NEC requirements for enclosure integrity when sealing unused openings.
