Asc Engineered Solutions 830518601 Black Steel Close Nipple

Product Description

The ASC ENGINEERED SOLUTIONS 830518601 is a black steel extra heavy (XH) close nipple designed for threaded pipe assemblies in plumbing, HVAC, gas distribution, and industrial piping systems. At 3/4 inch nominal pipe size with a close-cut length of 1-3/8 inches, this nipple provides the shortest possible threaded connection between two fittings or valves, leaving no exposed unthreaded pipe between the mating components. The extra heavy wall designation means increased pressure handling and wall thickness compared to standard pipe nipples. Licensed plumbers and pipefitters are the primary installers in commercial and industrial applications.

This close nipple is suited for residential and light commercial gas lines, steam systems, compressed air lines, and water distribution piping where a tight, near-zero-length connection is required between two threaded components. The 3/4 inch size fits common main supply and branch lines across a wide range of plumbing and mechanical systems. Its black steel construction makes it appropriate for natural gas and propane service, as well as fire suppression and hydronic heating piping where black iron fittings are code-acceptable or required.

Key Features

• Extra heavy (XH) wall construction for increased pressure tolerance over standard-weight nipples
• Close-cut length of 1-3/8 inches allows minimal spacing between threaded fittings or valves
• Black steel material suitable for gas, steam, compressed air, and hydronic heating service
• 3/4 inch nominal pipe size fits common supply and branch line applications
• Fully threaded end-to-end per close nipple standard, maximizing thread engagement in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4 inch NPT threaded pipe systems in plumbing, HVAC, gas distribution, and industrial piping assemblies.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC). Shut off and depressurize the affected pipe system before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium — gas-rated sealant is required on fuel gas lines. Do not over-tighten close nipples, as the short thread engagement can make them difficult to remove once fully seated.
