Aluminium pipe nipple for fluid lines

This Zoro Select pipe nipple is a seamless aluminium fitting designed for air, non-potable water and oil applications. It suits maintenance teams and installers who need a lightweight, corrosion-resistant connector for low-pressure systems.

Threaded NPT ends fit Class 125 fittings

Both ends carry 1 1/2 inch NPT threads compatible with Class 125 fittings, so the nipple threads directly into existing pipework without adapters. The seamless 6063-T6 aluminium construction eliminates weld seams that could leak under vibration.

Rated 125 psi at 72 degrees F

The fitting handles a maximum operating pressure of 125 psi at 72 degrees F, making it suitable for sustained low-pressure duty rather than high-pressure spikes. Aluminium construction keeps weight down while maintaining structural integrity over long runs.

Questions about this item

How much pressure can the 1 1/2 in aluminum nipple handle during continuous operation?

The maximum operating pressure is 125 psi at 72 degrees F, so sustained use should stay at or below that limit.

Does the aluminum nipple get hot or noisy when fluid runs through it all day?

The seamless 6063-T6 aluminum construction has no moving parts, so it produces no noise and its temperature follows the fluid up to the 125 psi rating.

What thread standard must the mating fittings use to connect properly?

Both ends are cut to NPT, so the mating fittings must also be NPT threaded for a correct seal.
