Appleton 4QG-75 O-ring Assembly 3/4 Inch

Product Description

The APPLETON 4QG-75 is a 3/4-inch o-ring assembly designed to provide a reliable seal at conduit fittings and enclosure connections in electrical installations. This component creates a compression seal that prevents moisture, dust, and contaminants from entering at threaded conduit joints. Weighing 1 pound and measuring 5.5 inches by 5.3 inches with a profile of 0.030 inches, it is a low-profile sealing element built for use in both standard and wet-location electrical applications. Licensed electricians and maintenance technicians working with conduit systems are the primary installers of this assembly.

This o-ring assembly is suited for use in residential, commercial, and light industrial electrical conduit systems where a watertight or raintight seal is required at a 3/4-inch fitting interface. It is commonly used during installation or replacement of conduit fittings, hubs, and enclosures where maintaining an environmental seal is a code requirement or a design specification.

Key Features

• 3/4-inch nominal size fits standard 3/4-inch conduit fitting connections
• Low-profile at 0.030 inches thickness for flush seating at fitting faces
• Designed to maintain a compression seal against moisture and particulate ingress
• Lightweight construction at 1 pound for easy handling and installation
• Compatible with Appleton OZ-G series fittings and similarly sized conduit hardware

Compatibility

Designed as an OEM-style replacement o-ring assembly for 3/4-inch conduit fittings and enclosure connections in standard electrical installation applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits before servicing any conduit fitting or enclosure. Seat the o-ring fully and evenly in the fitting groove before tightening to avoid pinching or distorting the seal. Do not reuse a compressed or damaged o-ring, as a compromised seal will not maintain a reliable environmental barrier.
