Silver seamless aluminium pipe with male NPT threads both ends, three feet long

Zoro Select

Zoro Select Aluminum Pipe 1 1/2 in NPT 3 ft

SKU CH-8Y43-3RCN1

Seamless aluminium pipe with male NPT threads on both ends, rated to 125 psi at 72 °F and corrosion-resistant

  • Corrosion-resistant 6063-T6 aluminum withstands moisture
  • Seamless Schedule 40 construction handles 125 psi at 72 °F
  • Male NPT threads on both ends simplify air-line connections
  • 1 5/8 in bore ensures unrestricted flow
  • 3 ft length suits standard plumbing runs

1 1/2 in NPT Aluminum Pipe for Air Lines

This three-foot pipe is built from seamless 6063-T6 aluminum and carries a Schedule 40 rating. Male NPT threads on both ends allow direct connection to standard fittings in compressed-air systems. The 125 psi pressure limit at 72 °F suits typical shop supply lines. Corrosion-resistant construction supports long service in dry or lubricated air.

Seamless 6063-T6 tube with threaded ends

Seamless extrusion removes internal weld seams that can trap debris or create leak paths. Male NPT threads on each end mean the pipe screws straight into couplers, valves or drops without extra adapters. The 1 29/32 in outside diameter fits Schedule 40 clamps and hangers. Aluminum weight eases overhead routing compared with steel pipe.

Schedule 40 pressure ceiling at 125 psi

The 125 psi ceiling at 72 °F defines the safe working envelope; pressure spikes above this risk permanent deformation. Temperature excursions above the rated point reduce the allowable pressure further. Threaded NPT joints demand sealant and proper torque to hold the rated seal. Installers needing higher pressures or larger diameters must select a different pipe class.

Questions about this item

What pressure does the 1 1/2 in NPT aluminum pipe handle at 72 Degrees F?

The maximum operating pressure is 125 psi at 72 Degrees F, as rated for the Schedule 40 aluminum construction.

What are the exact outside diameter and length for mounting clearance?

The pipe has an outside diameter of 1 29/32 in and an overall length of 3 ft, with male NPT threads on both ends.

How do I seal the NPT threads correctly without damaging the aluminum?

Apply PTFE tape or pipe thread sealant to the male NPT threads, then tighten by hand plus one to two turns with a wrench; over-tightening can crack the 6063-T6 aluminum.
