The AQUALINE GPN-50-80 is a Schedule 40 galvanized steel pipe nipple sized at 1/2 inch nominal diameter by 8 inches in length. It is used to extend or connect threaded pipe runs in water supply, gas distribution, and general plumbing systems. The hot-dip galvanized zinc coating provides corrosion resistance in both wet and moderately corrosive service environments. Both ends carry standard NPT threads for direct make-up with fittings, valves, and pipe. Licensed plumbers and pipefitters are the primary installers, though the part is straightforward enough for knowledgeable tradespeople in HVAC and mechanical work.
This nipple is suited for residential and light commercial plumbing installations where a short threaded extension is needed between fittings. Common applications include water service lines, boiler supply and return connections, gas piping laterals, and mechanical room pipe runs. The 8-inch close-cut length fills the gap between a close nipple and a full pipe section without requiring field cutting or threading.
Designed as an OEM-style replacement or new-installation component for 1/2 inch NPT threaded pipe systems in residential and commercial plumbing, HVAC, and gas piping applications.
Installation is performed by a licensed plumber or pipefitter in accordance with the International Plumbing Code or International Fuel Gas Code as applicable to the service. Always shut off and depressurize the line before threading or unthreading any nipple. Apply an approved thread sealant or PTFE tape to the male threads before make-up. Do not use galvanized nipples in systems where regulations prohibit zinc-coated pipe, such as certain natural gas distribution systems governed by local code.
