Asc Engineered Solutions 830552329 Black Steel Xh Nipple 4x4

Product Description

The ASC Engineered Solutions 830552329 is a 4-inch by 4-inch extra heavy (XH) black steel nipple used to connect threaded pipe sections in gas, industrial, and mechanical piping systems. The extra heavy wall thickness provides added strength for higher-pressure or higher-stress applications compared to standard-weight nipples. Fabricated from black steel, this nipple is a common choice for gas distribution, fire suppression headers, and industrial fluid lines. It is typically installed by licensed plumbers, pipefitters, and mechanical contractors working on commercial or industrial piping assemblies.

This nipple is suited for use in commercial and industrial piping systems where a close or short extension between two threaded fittings is required. The 4-inch by 4-inch size fits larger-diameter pipe runs common in main gas supply lines, industrial process piping, and fire protection systems. The extra heavy designation makes it appropriate for applications that demand greater wall strength than standard or schedule 40 weight nipples can provide.

Key Features

• Extra heavy (XH) wall construction for increased pressure and stress resistance
• Black steel material suitable for gas, steam, and industrial fluid service
• 4-inch by 4-inch size fits large-diameter threaded pipe connections
• Threaded both ends for direct connection between couplings, valves, or fittings
• 5.00 pounds per unit, indicating substantial wall thickness consistent with XH designation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 4-inch threaded black steel piping systems, consistent with ASME and ASTM standards for extra heavy pipe nipples.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where relevant. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape rated for the intended service medium to all male threads before makeup. Do not use this fitting beyond its rated service conditions or in applications for which black steel is not approved.
