Nipples 330041203 Black Steel Close Nipple 2.5 in

Product Description

The NIPPLES 330041203 is a domestic black steel close nipple with a 2.5-inch nominal pipe size. A close nipple is threaded end-to-end with no unthreaded center, making it useful for connecting fittings as tightly as possible. Black steel construction suits low-pressure gas, air, and hydronic piping systems where corrosion protection is not required from the pipe itself. Plumbers, pipefitters, and HVAC technicians install this type of nipple in both residential and light commercial applications.

This close nipple is suited for use in gas distribution, steam, air, and water piping systems where a minimal-length threaded connector is needed between two fittings. The close configuration eliminates any exposed center section, which is valuable in tight-clearance installations. It is appropriate for residential and commercial rough-in plumbing and mechanical systems where black steel pipe is specified.

Key Features

• Close (end-to-end threaded) configuration for maximum space savings between fittings
• 2.5-inch nominal pipe size fits standard NPT fittings and couplings
• Domestic black steel construction for use in gas, air, steam, and hydronic systems
• Compatible with standard NPT threaded fittings without additional adapters

Compatibility

Designed as an OEM-style replacement or standard-stock close nipple for 2.5-inch NPT black steel piping systems in residential and commercial mechanical installations.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC, or IPC requirements. Shut off all gas or fluid supply and relieve system pressure before removing or installing any threaded pipe component. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
