Bmi Usa 4655 Brass Nipple 1x5.5 in Lead Free

Product Description

The BMI USA 4655 is a lead-free brass threaded nipple used to connect sections of pipe in plumbing, HVAC, and mechanical systems. Measuring 1 inch in diameter and 5.5 inches in length, this nipple provides a durable, corrosion-resistant joint between threaded fittings, valves, and pipe runs. Constructed from solid brass with a red finish, the 4655 meets lead-free standards required for potable water applications. At 0.68 pounds, it is a compact component suited for both residential and light commercial installations where a reliable threaded connection is needed.

This brass nipple is appropriate for use in potable water supply lines, hydronic heating systems, gas distribution piping, and general plumbing rough-in work. Its threaded ends allow direct connection to standard fittings, valves, and manifolds without additional adapters. Licensed plumbers and pipefitters typically install this type of nipple during new construction, remodel, or repair work wherever a short, fixed-length pipe extension is required between two threaded ports.

Key Features

• Lead-free brass construction meets potable water installation requirements
• 1 inch diameter x 5.5 inches length for precise, fixed-run connections
• Red finish for quick visual identification on the job
• Threaded ends for direct connection to standard fittings and valves
• Solid brass material provides corrosion resistance in wet environments

Compatibility

Designed as a standard threaded brass nipple replacement or new-install fitting for 1-inch threaded pipe systems in residential and commercial plumbing and mechanical applications.

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 relieve system pressure before threading the nipple into place. Apply appropriate thread sealant or PTFE tape to the male threads prior to assembly. Do not over-tighten, as brass threads can be damaged by excessive torque.
