The NSI INDUSTRIES 260 is a 1/2 inch compression-style EMT coupling used to join two sections of electrical metallic tubing in conduit raceway systems. The compression fitting design creates a secure, rain-tight mechanical connection without the need for set screws, making it well suited for wet and damp locations. Licensed electricians and electrical contractors install this coupling during rough-in and conduit installation work in residential, commercial, and light industrial settings. The compact form factor fits standard 1/2 inch EMT conduit and is a reliable choice for code-compliant conduit runs.
This coupling is used wherever 1/2 inch EMT conduit must be joined at a splice point, including panel feeds, device circuits, and branch circuit conduit runs. It is appropriate for both indoor and outdoor installations where a weatherproof or rain-tight conduit connection is required. The compression coupling is a common stock item for electrical contractors working on new construction and retrofit projects.
Designed as an OEM-style replacement and standard-fit coupling for 1/2 inch EMT conduit systems in residential and commercial electrical installations.
Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the affected conduit run before beginning work. Slide the coupling over the conduit ends and tighten the compression nuts by hand, then snug with pliers or a strap wrench to achieve a secure, rain-tight seal. Do not over-tighten, as this may deform the fitting or conduit.
