Aluminium pipe nipple, 1 1/2 in NPT, 3 in long, silver finish

Zoro Select

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

SKU CH-8YEK-YCHQ1

Aluminium pipe nipple with 1 1/2 in NPT threads and 3 in overall length for air, non-potable water and oils at 125 psi

  • Seamless 6063-T6 aluminium resists corrosion in air, water and oil systems
  • 125 psi rating at 72 °F handles standard pneumatic and hydraulic loads
  • 1 1/2 in NPT threads mate with Class 125 fittings for leak-free joints
  • 3 in overall length fits tight plumbing runs without extra couplings
  • Seamless construction eliminates weld defects that can weaken flow paths

Application fit

The Zoro Select pipe nipple connects 1 1/2 inch NPT threads in air, non-potable water and oil lines. Its seamless aluminium construction suits industrial maintenance crews and plant engineers who need a straight, leak-free joint.

Thermals, noise and power

The fitting contains no moving parts, generates no noise and draws no power during operation. Pressure-rated at 125 psi at 72 degrees Fahrenheit, it maintains seal integrity across the stated temperature range without thermal cycling concerns.

Bundled impact

No accessories, coatings or software are included with the nipple. The bare 6063-T6 aluminium finish means installers must supply their own thread sealant or tape to match the specific fluid and pressure requirements of each job.

Questions about this item

How do I install the 1 1/2 in NPT aluminum pipe nipple without damaging the threads?

Apply PTFE tape or pipe dope to the male NPT threads, then hand-tighten into the Class 125 fitting before using a wrench for one to two additional turns; over-tightening cracks the 6063-T6 aluminum.

What maintenance does the seamless aluminum nipple need over time?

Inspect the 1 29/32 in outside diameter and 1 5/8 in inside diameter for corrosion or deformation whenever the air, oil or non-potable water system is serviced; replace the nipple if thread galling or wall thinning appears.

At what pressure does the 3 in nipple reach its limit during continuous operation?

The maximum operating pressure is 125 psi at 72 Degrees F; sustained use above that rating risks failure of the seamless 6063-T6 aluminum construction.
