Southwire MNT-2763 Rigid Compression Coupling Malleable

Product Description

The SOUTHWIRE MNT-2763 is a no-thread malleable rigid compression coupling designed to join rigid metal conduit sections without the need for threaded ends. Machined from malleable iron, this coupling provides a secure, vibration-resistant connection that holds conduit in alignment in both indoor and commercial electrical installations. The 1-1/4 inch trade size fits standard rigid conduit of that diameter. Licensed electricians and electrical contractors install this fitting as part of a grounded metallic raceway system in compliance with NEC requirements.

This coupling is suited for use in rigid metal conduit systems found in commercial, industrial, and heavy-duty residential electrical installations. The compression design allows the fitting to be installed on conduit that has already been cut and deburred, without threading either end. It is a practical solution in retrofit and repair scenarios where threading equipment is not available on site or where conduit ends have been damaged and re-threading is not feasible.

Key Features

• No-thread compression design — connects rigid conduit without threading either end
• Malleable iron construction for strength and resistance to mechanical stress
• 1-1/4 inch trade size fits standard rigid metal conduit
• Maintains raceway continuity for grounding integrity
• Suitable for retrofit, repair, and new construction installations

Compatibility

Designed as an OEM-style replacement compression coupling for 1-1/4 inch rigid metal conduit systems in commercial and industrial electrical raceways.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC articles governing rigid metal conduit systems. De-energize the circuit and verify lockout before working on any existing raceway. Conduit ends should be cut square and deburred before seating into the coupling. Do not overtighten compression nuts beyond hand-firm plus a quarter turn without verifying manufacturer guidance, as excessive force can crack the fitting body.
