Merit Brass 8040-450 Aluminum Pipe Nipple Sch 40

Product Description

The MERIT BRASS 8040-450 is a Schedule 40 aluminum pipe nipple machined from 6061 aluminum alloy. It measures 2.5 inches in diameter and 4.5 inches in length, with threads on both ends for direct connection to standard pipe fittings. At 0.675 pounds, it is well-suited for installations where weight reduction matters without sacrificing structural integrity. This nipple is used by plumbers, pipefitters, and mechanical contractors working on fluid and gas distribution systems where corrosion resistance and light weight are priorities. OSHA-compliant construction makes it appropriate for commercial and industrial piping applications.

This pipe nipple is commonly installed in residential and light commercial plumbing, compressed air lines, and industrial process piping where aluminum is preferred over steel or brass. The 6061 alloy offers good machinability and resistance to corrosion in a wide range of environments. Threaded-both-ends construction allows it to connect inline between couplings, valves, or fittings without additional machining. It is well-suited for systems requiring frequent disassembly or where iron pipe would introduce unwanted weight or galvanic concerns.

Key Features

• 6061 aluminum alloy construction for corrosion resistance and reduced weight
• Schedule 40 wall thickness for standard pressure-rated piping systems
• Threaded on both ends for straightforward inline installation
• 2.5-inch nominal diameter by 4.5-inch length
• OSHA-compliant per listed standards
• Lightweight at 0.675 pounds for ease of handling in overhead or tight-space installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 aluminum piping systems using 2.5-inch nominal pipe size connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC or IFGC requirements for the system type. Shut off and depressurize the line fully before removing or installing any threaded fittings. Apply appropriate thread sealant or PTFE tape rated for the conveyed media before threading the nipple into fittings. Do not overtighten aluminum fittings, as the alloy is softer than steel and susceptible to thread damage under excessive torque.
