Aqualine GPN-125-80 Galvanized Steel Pipe Nipple Sch 40

Product Description

The AQUALINE GPN-125-80 is a Schedule 40 galvanized steel pipe nipple used in threaded piping systems across plumbing, HVAC, fire protection, and general industrial applications. Measuring 1.25 inches in diameter and 8 inches in length, it connects threaded fittings, valves, and equipment where a short rigid pipe section is required. The hot-dip galvanized coating provides corrosion resistance suitable for water supply, gas distribution, and outdoor or exposed piping runs. Licensed plumbers and pipefitters are the primary installers of this fitting type.

This nipple is suited for residential and light commercial piping systems where 1.25-inch Schedule 40 pipe threads are specified. Common applications include water service lines, gas branch lines, boiler connections, and equipment tie-ins. The 8-inch length provides enough exposed thread-to-thread clearance for standard union or valve connections without requiring an offset coupling. It is a stock fitting used in both new construction and retrofit service work.

Key Features

• Schedule 40 wall thickness rated for standard pressure service in threaded pipe systems
• Hot-dip galvanized steel construction provides corrosion resistance in wet and outdoor environments
• 1.25-inch nominal diameter with NPT threads on both ends
• 8-inch overall length suits close-quarter equipment connections and valve drops
• Suitable for water, gas, and general mechanical piping applications

Compatibility

Designed as a standard threaded replacement nipple for 1.25-inch NPT piping systems using Schedule 40 galvanized steel fittings and valves.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC or IFGC requirements depending on service type. Shut off the water or gas supply and depressurize the line before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to male NPT threads before assembly. Do not overtighten threaded connections, as this can crack fittings or distort thread engagement.
