Zoro Select 2in NPT Aluminum Pipe Nipple

This 4in Schedule 40 nipple is machined from seamless 6063-T6 aluminum with male NPT threads on both ends. It carries a 125 psi rating at 72 Degrees F and resists corrosion in compressed-air lines. The 2 3/8in outside diameter and 2 5/64in inside diameter match standard 2in nominal pipe dimensions.

Upgrade from threaded steel or brass nipples

Aluminum construction cuts weight and eliminates galvanic corrosion when joining dissimilar metals in air systems. The seamless Schedule 40 wall handles the same 125 psi working pressure as heavier steel equivalents. The jump makes sense when routing overhead runs where every kilogram counts or when the fluid path must stay free of rust contamination.

Sustained pressure and vibration performance

Seamless 6063-T6 alloy maintains its 125 psi rating continuously at 72 Degrees F without the creep seen in welded fittings. Male NPT threads on both ends seal reliably under repeated thermal cycling in shop-air networks. Corrosion-resistant surfaces keep the bore smooth so pressure drop stays predictable over long service intervals.

Questions about this item

What nominal pipe size and NPT thread does this 2 in aluminum nipple need to match for a proper fit?

It has a 2 in nominal pipe size with male NPT threads on both ends, so it fits Schedule 40 fittings with the same 2 in NPT connection.

How do you install this seamless aluminum nipple, and what threading step is often missed?

Thread each male NPT end into the matching female fitting using pipe sealant or tape on the threads, then tighten to the recommended torque; skipping the sealant is the common mistake that causes leaks.

When should this corrosion-resistant 6063-T6 aluminum nipple be inspected or replaced in a 125 psi air system?

Inspect annually for thread wear, corrosion or deformation; replace if the seamless wall shows pitting, cracks or if pressure testing exceeds the 125 psi @ 72 °F rating.
