Galvanized steel pipe nipple for fluid lines

This 1-1/4 inch Schedule 40 nipple connects threaded fittings in air, gas, oil, steam and water systems. The male NPT threads on one end and threaded-bevel end on the other suit standard plumbing assemblies. Grade A steel with a continuous weld provides structural integrity for industrial and residential installations.

Pressure rating and dimensional limits

Rated for 150 psi at 150 degrees Fahrenheit, the nipple handles typical low-pressure distribution duties. The 1 3/8 inch inside diameter and 1 21/32 inch outside diameter define the flow area and fitting clearance. At six inches overall length it bridges short gaps but cannot span longer runs without additional couplings.

Corrosion resistance and thermal behaviour

The galvanized coating protects the steel against rust in water and condensate service. Steel construction transmits heat readily, so the nipple reaches fluid temperature quickly during steam or hot-water use. No insulation or special thermal management is required for normal operating conditions.

Questions about this item

Will the 1-1/4" MNPT threads on this nipple mate with my existing Schedule 40 galvanized fittings?

Yes, the male NPT threads are cut to Schedule 40 dimensions so they engage standard galvanized couplings, elbows and tees of the same nominal size.

How can I confirm the nipple is holding pressure after I thread it into my air line?

Pressurise the system to its working limit of 150 psi at 150 °F and check each joint with leak-detect fluid; no bubbles means the continuous weld and threads are sealing.

Does the 6" TBE nipple come with thread sealant or gaskets, or must I buy them separately?

The box contains only the galvanized steel nipple; pipe-thread sealant or PTFE tape must be purchased separately for a leak-free assembly.
