Merit Brass 8008-300 Aluminum Pipe Nipple Sch 40

Product Description

The MERIT BRASS 8008-300 is a Schedule 40 aluminum pipe nipple machined from 6061 aluminum alloy and threaded on both ends. It measures 1/2 inch nominal pipe size by 3 inches in length and is designed for low- to medium-pressure piping systems where weight savings and corrosion resistance matter. The 6061 alloy offers solid machinability and weldability, making this nipple a dependable fitting choice for plumbing, pneumatic, and light industrial applications. Licensed plumbers and pipefitters are the primary installers, though experienced mechanical contractors work with fittings like this regularly.

This nipple is suited for residential and light commercial piping installations where aluminum is preferred over steel or brass — particularly in environments where moisture or mild corrosives could accelerate rust on ferrous fittings. The 1/2-inch nominal size and 3-inch length make it a common selection for instrument connections, compressed air lines, irrigation headers, and similar low-complexity piping runs. Both-ends threading allows straightforward inline connection between couplings, valves, or other threaded fittings without additional field threading.

Key Features

• 6061 aluminum construction — lightweight and resistant to corrosion in most non-caustic environments
• Schedule 40 wall thickness for standard-duty pressure applications
• Threaded on both ends for direct inline installation between threaded fittings
• 1/2 inch nominal pipe size by 3 inch length — a widely used short nipple dimension
• OSHA-compliant construction per supplier specifications

Compatibility

Designed as an OEM-style replacement or new-install fitting for 1/2-inch NPT threaded piping systems using Schedule 40 aluminum pipe fittings.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC or local mechanical code requirements. Shut off and depressurize the affected line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for aluminum fittings — avoid over-tightening, which can crack or distort aluminum threads. Do not use this fitting in systems carrying fluids or gases outside the pressure and temperature ratings specified for Schedule 40 aluminum pipe.
