Function and purpose

The Morris 14998 couples two lengths of conduit to form a continuous raceway. It is intended for use where a sealed, weather‑resistant joint is required between EMT conduit runs.

• Joins two conduit ends to create a continuous electrical raceway
• Provides a rain‑tight seal for exterior or damp locations when correctly installed

Construction and finish

This coupling is formed from heavy‑wall steel and finished with zinc plating. An internal sealing ring is incorporated to create the rain‑tight barrier between conduit sections.

• Material: Steel
• Finish: Zinc plated
• Feature: Internal sealing ring for rain‑tight performance
• Concrete‑tight design

Installation overview and compatibility

Install by sliding the coupling over the ends of the two conduit runs and tightening the compression mechanism to secure the joint and compress the internal seal. Proper tightening is required to achieve the rain‑tight and concrete‑tight performance.

The product is also UL listed for use with Rigid and IMC conduit; verify trade size and conduit type before installation.

• Slide coupling over conduit ends; tighten compression to form continuous run
