Anderson Metals 11153 Brass Pipe Nipple 1-1/2 in Npt

Product Description

The ANDERSON METALS 11153 is a close-pattern brass pipe nipple threaded on both ends, designed for use in low-pressure fluid and gas piping systems. Machined from red brass, it provides reliable corrosion resistance in wet or humid service environments. The nipple measures 1-1/2 inches overall length and carries NPT threads on both ends for leak-resistant, tapered-thread connections. Plumbers, pipefitters, and HVAC technicians install this type of fitting when connecting pipe runs or extending threaded assemblies with a minimal gap between fittings.

This nipple is suited for residential and light commercial plumbing, hydronic heating, compressed air, and similar low-to-moderate pressure piping applications. Its red brass construction makes it a practical choice in systems where iron or steel fittings would risk corrosion from water contact. The NPT thread form is the standard in North American pipe assemblies, making this nipple broadly compatible with standard threaded valves, couplings, and fittings across plumbing and HVAC installations.

Key Features

• Red brass construction resists corrosion in wet and humid service conditions
• NPT threads on both ends conform to North American taper-thread standards
• 1-1/2 inch overall length suits tight-clearance connections between fittings
• Threaded-both-ends design allows direct coupling of two threaded components
• Compact form factor appropriate for manifold assemblies and service connections

Compatibility

Designed as an OEM-style replacement or standard service fitting for residential and commercial threaded piping systems using NPT-standard connections.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and local plumbing code requirements. Shut off the water supply or depressurize the system before removing or installing any threaded fitting. Apply a listed pipe thread sealant or PTFE tape to the male NPT threads before assembly to achieve a leak-free joint. Do not over-tighten brass fittings, as red brass is softer than ferrous pipe and can crack under excessive torque.
