Nipples 331029603 Galvanized Pipe Nipple 1-1/4 in X 5 in Sch 40

Product Description

The NIPPLES 331029603 is a galvanized steel pipe nipple sized at 1-1/4 inches nominal with a 5-inch threaded-both-ends (TBE) configuration. Built to Schedule 40 specifications, it features continuous-weld construction from Grade A steel with a hot-dip galvanized finish for corrosion resistance. Rated for service at up to 150 psi at 150 degrees F, this nipple is suited for demanding system environments. Both ends are male NPT threaded for direct engagement with Schedule 40 fittings, valves, and couplings. Plumbers, pipefitters, and HVAC mechanics install this nipple as a short-run connector in a wide range of piped systems.

This nipple is rated for use in air, gas, non-potable water, oil, and steam service. Its galvanized coating makes it appropriate for exposed or moderately corrosive environments where bare steel would degrade prematurely. The 1-1/4-inch nominal size is common in commercial and light industrial piping systems, branch lines, and equipment connections. Manufactured in the United States, this nipple meets standard trade expectations for dimensional accuracy and thread quality in Schedule 40 carbon steel pipe assemblies.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the intended service medium. Shut off and depressurize the system fully before removing or installing any threaded nipple. Apply appropriate thread sealant or PTFE tape rated for the service type before making up the joint. Do not over-tighten threaded connections; use a backup wrench to prevent stress on adjacent fittings.
