GLNP150500 — 1-1/2" x 5" Galvanized Conduit Nipple for Rigid/IMC Runs

GLNP150500 — 1-1/2" x 5" Galvanized Conduit Nipple for Rigid/IMC Runs

If you're tying two boxes together or stitching a rigid conduit run through a tight knockout, the GLNP150500 gets you a clean 5" connection in 1-1/2" trade size, NPT-threaded on both ends, no cutting or threading in the field required. It's hot-dip galvanized, so it holds up outside, underground vaults, wet locations, wherever you're running it.

This is a standard rigid/IMC nipple, UL 6 listed and built to ANSI C80.1 dimensions, so it threads straight into your existing couplings, LBs, and enclosures without any surprises.

Common Applications

• Joining two enclosures or boxes at a fixed spacing
• Extending a rigid or IMC run through a wall or panel knockout
• Service entrance and panel-to-meter connections
• Any job where you need a factory-threaded nipple instead of field-threading pipe

Key Features

• Pre-threaded both ends: Skip the field threading — drops straight into your couplings and hubs.
• Hot-dip galvanized: Inside and out, holds up in wet locations and outdoor runs.
• UL 6 listed: Inspector-ready, no questions on code compliance.
• ANSI C80.1 sized: Matches your standard 1-1/2" rigid/IMC fittings every time.

FAQ

What's a 1-1/2 x 5 conduit nipple for?
Connecting two boxes or extending a rigid/IMC run at a fixed 5" length, NPT-threaded both ends.

Will inspectors pass this?
It's UL 6 listed and built to ANSI C80.1, so it's code-compliant for rigid metal conduit installations.

Threads cut or rolled?
Standard NPT thread, factory-cut on both ends — no field threading needed.

Good for outdoor or wet locations?
Yes — hot-dip galvanized finish is rated for outdoor and wet-location use.

Does it fit standard 1-1/2" rigid couplings?
Yes, it's sized to ANSI C80.1, so it threads into any standard 1-1/2" rigid/IMC coupling or hub.

RMC or IMC — which does this work with?
Both. It's threaded and sized for use on rigid metal conduit (RMC) and intermediate metal conduit (IMC).
