Bmi Usa 4255 Brass Nipple Lead Free 1/4 X 5.5 Inches

Product Description

The BMI USA 4255 is a lead-free brass threaded nipple designed for use in plumbing distribution systems where safe, durable pipe connections are required. Measuring 1/4 inch in diameter and 5.5 inches in length, this nipple provides a reliable threaded connection between fittings, valves, and pipe runs. Constructed from brass with a red finish, it delivers corrosion resistance suitable for potable water, hydronic, and general plumbing applications. Licensed plumbers and mechanical contractors are the primary installers of this type of fitting.

This nipple is suited for residential and light commercial plumbing installations where a short close nipple or extension is needed between threaded components. It is commonly used in water supply lines, boiler piping, and general mechanical rough-in work. Its lead-free construction makes it appropriate for potable water systems in compliance with lead-free plumbing regulations in effect across most jurisdictions in North America.

Key Features

• Lead-free brass construction meets potable water safety requirements
• 1/4 inch diameter with 5.5 inch body length for precise fitment in tight runs
• Threaded ends for standard NPT connections to valves, fittings, and pipe
• Red finish for easy identification in multi-pipe installations
• Lightweight at 0.21 pounds, reducing handling fatigue during high-volume rough-in

Compatibility

Designed as an OEM-style replacement or standard-fitment nipple for 1/4 inch NPT threaded plumbing systems in residential and commercial mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before replacing or installing any threaded fitting. Apply thread sealant tape or pipe compound to the male threads before assembly, and tighten to hand-snug plus appropriate wrench turns without over-torquing brass threads. Inspect for leaks after restoring system pressure.
