1-1/4" MNPT x 8" TBE Galvanized Steel Pipe Nipple
This Schedule 40 steel nipple connects threaded fittings in air, gas, non-potable water and oil lines. The galvanized coating resists corrosion in damp environments. Rated for 150 psi at 150 Degrees F, it suits standard low-pressure plumbing and industrial piping. Manufactured in the USA to Grade B steel specification.
Who this suits and who should look elsewhere
Installers needing a 1-1/4 inch nominal pipe size with male NPT threads on both ends will find this nipple fits directly. It is not for potable water systems or steam service. Buyers requiring higher pressure ratings, different thread types or longer lengths should select another fitting.
Capacity and headroom
The 1 3/8 inch inside diameter passes typical residential and light commercial flow volumes without restriction. At 150 psi maximum operating pressure it handles standard municipal and compressor-fed supplies comfortably. Beyond that pressure or in steam applications the rating is exceeded and a heavier-wall or certified component is required.

Questions about this item
What pipe thread size must the existing fitting have to accept the 1-1/4" MNPT end?
The fitting must provide a matching 1-1/4 inch female NPT thread for the nipple's male end to seal properly.
Will the 1 3/8 inch inside diameter restrict flow in a legacy 1-1/4 inch nominal steel system?
No, the 1 3/8 inch bore matches the standard Schedule 40 internal dimension for 1-1/4 inch nominal pipe, so flow remains consistent.
How can I confirm the galvanized coating is intact after threading the nipple into place?
Inspect the 1 21/32 inch outside diameter for continuous zinc coverage; no bare steel should show at the threads or along the welded seam.
