Merit Brass 8008-450 Aluminum Pipe Nipple Sch 40

Product Description

The MERIT BRASS 8008-450 is a 6061 aluminum pipe nipple designed for threaded piping assemblies in plumbing, industrial, and mechanical systems. It measures 1/2 inch nominal diameter by 4.5 inches in length and is manufactured to Schedule 40 wall thickness. Both ends carry full NPT threads, allowing direct connection to fittings, valves, or other threaded pipe components. At 0.104 pounds, it is lightweight without sacrificing the strength expected from 6061-grade aluminum. Licensed plumbers and pipefitters install this type of nipple as a short extension or close-off piece within a piping run.

This nipple suits residential and light commercial plumbing, irrigation, compressed air, and low-pressure fluid systems where aluminum is preferred over steel or brass for corrosion resistance or weight savings. The 1/2 inch size is among the most common in trade work, fitting standard pipe fittings, tees, elbows, and valves across a wide range of applications. It is sold individually and is well suited for both new construction and repair work requiring a precise, short pipe extension.

Key Features

• 6061 aluminum construction for corrosion resistance and reduced weight
• Schedule 40 wall thickness for standard-duty service
• Threaded on both ends for direct connection to NPT fittings
• 1/2 inch nominal diameter fits the most common trade pipe fittings
• Lightweight at 0.104 pounds, reducing load in overhead or portable assemblies

Compatibility

Designed as an OEM-style replacement or new-installation component for 1/2 inch NPT threaded piping systems where Schedule 40 aluminum pipe nipples are specified.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or local mechanical code requirements. Shut off system pressure and drain the line before removing or installing any threaded pipe component. Use appropriate thread sealant or PTFE tape rated for aluminum and the service fluid. Avoid over-torquing aluminum threads, as the material is softer than steel and susceptible to thread damage if over-driven.
