Bmi Usa 4478 Lead Free Brass Ready Cut Pipe 18 Inches

Product Description

The BMI USA 4478 is a lead-free brass ready cut pipe measuring 18 inches in length. It features male threaded ends sized at 1/2 inch, making it a direct-install solution for plumbing connections where a fixed-length, pre-cut nipple is required. Constructed from solid brass with a red finish, this pipe is suited for potable water systems where lead-free compliance is mandatory. Licensed plumbers and journeymen install this type of fitting in both residential and light commercial supply lines.

This ready cut pipe is commonly used in water supply rough-in work, fixture connections, and branch line assemblies. The 18-inch length fills a gap between standard close nipples and longer galvanized or copper runs, making it a practical choice when a rigid, corrosion-resistant brass fitting is needed at a specific distance. Its threaded construction allows straightforward installation with pipe wrenches and appropriate thread sealant or PTFE tape.

Key Features

• Lead-free brass construction meets potable water safety requirements
• 18-inch fixed length eliminates field cutting for standard rough-in scenarios
• 1/2 inch threaded ends for compatibility with standard pipe fittings and valves
• Red finish for quick visual identification in multi-pipe installations
• Solid brass material resists corrosion in water supply applications

Compatibility

Designed as an OEM-style replacement or direct-install brass threaded pipe nipple for residential and light commercial plumbing water supply systems using 1/2 inch threaded connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before removing or installing any threaded pipe. Apply PTFE tape or pipe thread sealant to male threads before making up the joint, and tighten with pipe wrenches to avoid cross-threading or over-stressing the fitting. Do not use on steam or high-pressure gas lines.
