Southwire 153M 1 Inch Metal Insulated Squeeze Flex Connector

Product Description

The SOUTHWIRE 153M is a 1-inch metal insulated squeeze-type flexible conduit connector designed for securing flexible metal conduit to electrical boxes, enclosures, and panels. The squeeze connector design allows for fast, tool-free installation by hand, eliminating the need for a screwdriver or nut driver during the termination step. An insulated throat protects wire insulation from abrasion at the conduit entry point. Licensed electricians and electrical contractors install this fitting in both new construction and retrofit applications where flexible conduit transitions to a junction box or panel knockout.

The 153M is suited for residential and light commercial electrical installations where flexible metal conduit connects to outlet boxes, junction boxes, or load centers. The 1-inch trade size accommodates standard 1-inch flexible metal conduit runs. This connector is a common component in branch circuit wiring, equipment connections, and motor feed applications where vibration isolation or routing flexibility is required.

Key Features

• 1-inch trade size fits standard 1-inch flexible metal conduit
• Squeeze-type design allows fast hand-tightened installation without tools
• Insulated throat protects wire and cable insulation from abrasion at entry
• Metal construction provides mechanical strength and grounding continuity
• Fits standard knockout openings in electrical enclosures and panels

Compatibility

Designed as an OEM-style replacement and standard fitting for use with 1-inch trade size flexible metal conduit in residential and light commercial electrical installations.

Installation Notes

Installation is performed by licensed electricians in accordance with NEC requirements for flexible metal conduit terminations. De-energize all circuits and verify the absence of voltage before working inside any enclosure. Insert the connector through the knockout, secure the locknut firmly, and squeeze the connector body onto the conduit end to complete the termination. Inspect the insulated throat for damage before installation to ensure wire protection is intact.
