SKU CH-81VN-6VP64

Galvanized steel pipe nipple with 1-1/2 inch MNPT close TBE ends for air, gas and potable water systems rated to 300 psi at 150 degrees F

  • Galvanised coating resists corrosion in air, gas and potable water systems
  • Welded steel construction rated for 300 psi at 150 °F operating pressure
  • Schedule 40 wall thickness handles steam up to 150 psi at 350 °F
  • 1-1/2 inch MNPT close nipple fits tight spaces with 1 57/64 inch outside diameter
  • California Proposition 65 warning for cancer and reproductive harm chemicals

Purpose & Fit

This galvanized steel pipe nipple joins two female NPT fittings in air, gas or potable-water lines. It is sized for Schedule 40 systems with a 1-1/2 inch nominal bore and a close TBE length of 1 3/4 inches. The welded construction suits permanent installations where thread sealant provides the joint seal.

Critical Spec

The fitting carries a maximum operating pressure of 300 psi at 150 degrees F and a maximum steam pressure of 150 psi at 350 degrees F. Exceeding either limit risks joint failure, so verify system design pressure and temperature before installation.

Sustained Load Behaviour

Electric-resistance welded seams and the galvanized coating maintain corrosion resistance during continuous exposure to pressurised water, air or steam at rated conditions. The steel wall thickness defined by Schedule 40 resists creep and thread deformation over long service periods.

Questions about this item

How much pressure can the 300 psi rating actually handle in a live air or water line?

The nipple is rated for 300 psi at 150 degrees F for air, gas or potable water, and 150 psi at 350 degrees F for steam service.

What does the Schedule 40 designation limit on thread compatibility?

Schedule 40 sets the wall thickness so the nipple mates with any Schedule 40 fitting or valve using 1-1/2 inch MNPT threads.

Will the 1 57/64 inch outside diameter and 1 3/4 inch overall length clear a standard 1-1/2 inch pipe bracket?

The 1 57/64 inch OD and 1 3/4 inch close length fit typical Schedule 40 brackets and leave minimal exposed thread for tight installations.
