Asc 4354001200 Black Steel Xh Close Nipple 1/2 in

Product Description

The ASC ENGINEERED SOLUTIONS 4354001200 is a black steel seamless extra-heavy close nipple sized at 1/2 inch with an approximate overall length of 1 inch. Close nipples are threaded end-to-end with minimal or no unthreaded center, making them the right choice when two fittings or valves need to be joined with the shortest possible pipe segment. Manufactured from black steel to ASTM A106B seamless standards, this nipple is built for demanding pressure and temperature service in gas, steam, and industrial piping systems. It weighs 0.07 pounds per piece. Licensed plumbers and pipefitters are the typical installers for this type of fitting.

This close nipple is suited for residential and commercial gas distribution, steam lines, compressed air, and hydronic heating applications where a compact, rigid threaded connection is required. The extra-heavy wall thickness provides additional margin for high-pressure service compared to standard-weight nipples. It is commonly installed at burner manifolds, valve inlets, and equipment connections where space between threaded components is limited. Import-sourced product.

Key Features

• Black steel construction resists corrosion in dry gas and steam service
• Seamless ASTM A106B tube stock for uniform wall integrity
• Extra-heavy wall rating for elevated pressure applications
• Close pattern — end-to-end threading minimizes installed length
• 1/2 inch NPT thread size with approximately 1 inch overall length

Compatibility

Designed as a standard-pattern 1/2 inch NPT threaded close nipple for use in black steel piping systems requiring extra-heavy wall fittings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IFGC or IPC. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape rated for the service medium to the male threads before assembly. Do not over-tighten close nipples, as the short thread engagement leaves little room for correction if threads are damaged.
