Merit Brass 2132-450 Brass Pipe Nipple 2x4.5 in

Product Description

The MERIT BRASS 2132-450 is a solid brass pipe nipple sized at 2 inches by 4.5 inches, designed for use in plumbing, HVAC, and general piping systems where a short threaded connector is needed between fittings, valves, or equipment ports. Brass nipples are chosen for their corrosion resistance, machinability, and reliable thread engagement in both hot and cold water service. This nipple weighs 1.44 pounds, indicating a full, heavy-wall brass construction suitable for demanding trade applications. It is installed by licensed plumbers, pipefitters, and HVAC mechanics working on water supply, gas distribution, and fluid transfer systems.

This nipple is suited for residential and light commercial plumbing and HVAC installations where a 2-inch threaded connection is required. Typical applications include connecting valves, unions, or manifolds in water supply lines, hydronic heating systems, and compressed air distribution. The 4.5-inch length provides clearance for wrenching and accommodates standard close-coupled fitting assemblies without requiring a reducing coupling.

Key Features

• Solid brass construction offers corrosion resistance in water, gas, and fluid service
• 2-inch by 4.5-inch dimensions suit standard pipe schedules and fittings
• Threaded ends allow direct connection to valves, couplings, and equipment ports
• 1.44-pound weight reflects heavy-wall, full-material brass build

Compatibility

Designed as an OEM-style replacement or standard-service brass nipple for 2-inch threaded pipe systems in residential and commercial plumbing, HVAC, and fluid distribution applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IPC standards. Shut off supply pressure and depressurize the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before makeup. Use proper pipe wrenches sized for 2-inch pipe to avoid deforming the fitting body.
