Merit Brass 2112-001 Brass Close Nipple 3/4 Inch

Product Description

The MERIT BRASS 2112-001 is a close brass nipple designed for threaded pipe assemblies in plumbing, HVAC, and general piping systems. A close nipple connects two female-threaded fittings with minimal spacing, as threads run the full length of the nipple body with no unthreaded center section. This 3/4 inch size nipple measures 1-3/8 inches in overall length and is machined from brass for corrosion resistance and reliable sealing in both liquid and gas service applications. Plumbers and pipefitters install this fitting where tight, back-to-back threaded connections are required.

This close nipple is suited for residential and light commercial plumbing rough-in, HVAC condensate and water supply lines, gas appliance piping, and industrial fluid handling where 3/4 inch NPT connections are specified. Its short body makes it the correct choice when space between two fittings is at a minimum and a standard or long nipple will not fit the assembly layout.

Key Features

• Close-pattern body: full-length threads with no unthreaded center, minimizing installed length to 1-3/8 inches
• 3/4 inch nominal pipe size for high-flow plumbing and gas piping applications
• Brass construction provides corrosion resistance in water, steam, and compatible gas service
• Lightweight at 0.10 pounds per fitting, reducing load in overhead or wall-mounted assemblies

Compatibility

Designed as an OEM-style replacement or standard-stock close nipple for 3/4 inch NPT threaded pipe systems in residential and commercial plumbing and HVAC applications.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and IFGC code requirements for the intended service. Apply thread sealant tape or pipe dope rated for the specific service medium before threading the nipple into female fittings. Hand-tighten first, then use a pipe wrench to achieve a leak-free connection without overtightening, which can crack fittings or distort threads. Shut off and depressurize the supply line fully before removing any existing fitting or nipple.
