Appleton STG-25 O-ring Assembly 1/4 Inch

Product Description

The APPLETON STG-25 is a 1/4 inch o-ring assembly designed to provide reliable sealing in conduit and fitting applications. O-ring assemblies of this type create a pressure-resistant, moisture-resistant seal at threaded connection points, preventing ingress of water, dust, and contaminants into electrical enclosures and conduit systems. This component is commonly installed by licensed electricians during conduit rough-in, fitting maintenance, or enclosure service work where a secure threaded seal is required.

The STG-25 is suited for use in commercial and industrial electrical installations where conduit fittings require a compression seal at the threaded joint. It is appropriate for environments where vibration, moisture exposure, or code-required sealing at conduit entry points makes a properly seated o-ring essential. This assembly is typically used during new installation or as a replacement seal during fitting service.

Key Features

• 1/4 inch o-ring sizing for precise fit at matching threaded fittings
• Seals conduit connections against moisture and contaminant ingress
• Lightweight design at approximately 1 pound per 100 units
• Compatible with standard threaded conduit fitting applications

Compatibility

Designed as an OEM-style replacement o-ring assembly for 1/4 inch threaded conduit fittings and enclosure connections. Consult fitting documentation to confirm thread size and groove dimensions before installation.

Installation Notes

Installation is performed by a licensed electrician. De-energize all circuits and verify the absence of voltage before servicing any conduit fitting or enclosure connection. Inspect the seating groove for damage or debris before installing the new o-ring assembly. Do not over-torque the fitting after seating the o-ring, as excessive force can damage the seal and compromise the connection.
