Overview

The Appleton STNM 90 degree liquidtight connector is a three-piece industrial fitting designed for dependable connections to nonmetallic flexible conduit. With floating sleeve technology, this connector reduces installation time while ensuring a pull-proof seal against oil, water, dirt, and chemicals—ideal for wet locations, Class I Division 2 hazardous areas, and demanding industrial environments.

Key Features

• Floating Sleeve Design: Exclusive "floating sleeve" reduces installation time when connecting to nonmetallic flexible conduit.
• Deep-Threaded Ferrule: Positive, pull out proof seal formed by the deep-threaded ferrule that bites into the inner wall of the conduit.
• Self-Aligning Compression Nut: Sleeve is held captive within a compression nut that allows it to move freely and self-align with the conduit; the nut rides only on the sleeve and not on the conduit.
• Three-Piece Assembly: Fast disassembly permits harness preparation in advance for quick field connections.
• UL & CSA Certified: Approved for liquid-tight, rain-tight, and oil-tight applications.
