Aqualine GPN-125-100 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-125-100 is a Schedule 40 galvanized steel pipe nipple sized at 1.25 inches nominal diameter by 10 inches in length. It is a short threaded pipe section used to connect fittings, valves, and equipment in water supply, gas distribution, and industrial piping systems. The hot-dip galvanized coating provides corrosion resistance for use in wet or moderately corrosive environments. Both ends carry standard NPT threads for a secure, leak-resistant connection. Plumbers, pipefitters, and mechanical contractors install this type of nipple as a standard component in above-ground and exposed piping assemblies.

This nipple is suited for residential and light commercial plumbing, fire protection, and general-purpose piping applications where a 1.25-inch Schedule 40 galvanized fitting is required. Typical uses include drop nipples, riser connections, valve extensions, and equipment tie-ins. The 10-inch length accommodates installations where a close or short nipple would not provide adequate clearance between fittings or where a specific offset is needed in the piping layout.

Key Features

• Schedule 40 wall thickness for standard-service pressure ratings
• Galvanized steel construction resists corrosion in wet and exposed environments
• 1.25-inch nominal diameter with NPT threads on both ends
• 10-inch body length provides clearance for valve handles, unions, or equipment flanges
• UPC listed for code-compliant installations

Compatibility

Designed as an OEM-style replacement and standard-stocking component for Schedule 40 galvanized threaded piping systems using 1.25-inch NPT connections.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC requirements for the intended service. Shut off and depressurize the supply line before removing or installing any threaded pipe section. Apply an approved thread sealant or PTFE tape to the male NPT threads before assembly and tighten with pipe wrenches to a snug, wrench-tight fit. Do not over-torque, as this can crack fittings or strip threads.
