5404-16-06

Description & Features

Designed for reducing connections between mismatched thread sizes, this hex nipple transitions from a 1-inch male pipe thread to a 3/8-inch male pipe thread in a compact, double-ended configuration. The hex body provides a secure grip point for wrench installation, making it well-suited for tight assemblies where controlled torque is required. Manufactured by Brennan Industries, the 5404-16-06 is a reliable choice for hydraulic and industrial fluid systems requiring a threaded male-to-male reducer fitting.

The external hex profile simplifies installation and removal without sacrificing a low-profile footprint. Applications include hydraulic manifolds, valve bodies, cylinders, and other industrial fluid circuit components where a step-down thread transition is needed between ports or fittings of different sizes.

Question by: Ronnie C on Jul 31, 2025, 10:18 AM

Will this fitting work to connect a 1 inch pipe down to a 3/8 inch? Just want to make sure I'm understanding correctly.

That's precisely what this hex nipple is designed for. It creates a transition between a 1-inch male pipe thread and a 3/8-inch male pipe thread.
