Value Collection 590-035XSBC Black Pipe Nipple Sch 80

Product Description

The VALUE COLLECTION 590-035XSBC is a Schedule 80 seamless black pipe nipple designed for use in industrial and commercial piping systems. With a 3-inch diameter and a 3.5-inch length, this close-cut nipple provides a short, rigid connection between fittings, valves, or threaded pipe sections. The seamless construction eliminates weld seams, improving pressure integrity and reducing potential leak points. The black finish is standard for natural gas distribution, steam lines, and compressed air systems. Plumbers, pipefitters, and mechanical contractors install this type of nipple during new construction and maintenance work on threaded iron pipe assemblies.

This nipple is suited for residential and commercial plumbing, gas distribution, steam, and compressed air applications where Schedule 80 wall thickness is required for higher pressure ratings. The 3-inch diameter makes it appropriate for main supply lines and branch connections in larger-scale mechanical systems. It threads directly into Schedule 80-compatible fittings, unions, and valves using standard NPT threads. The black finish is conventional for gas piping applications and helps distinguish gas lines from water supply lines in the field.

Key Features

• Schedule 80 wall thickness for higher working pressure compared to Schedule 40
• Seamless construction eliminates weld seams for improved pressure integrity
• 3-inch nominal pipe diameter for main supply and larger branch line connections
• 3.5-inch overall length suits close-clearance connection applications
• Black finish standard for gas distribution and steam line identification

Compatibility

Designed as an OEM-style replacement or standard-stock fitting for Schedule 80 threaded iron pipe systems using 3-inch nominal NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes, including IFGC and IPC requirements. Shut off the gas or fluid supply and depressurize the line fully before removing or installing any threaded nipple. Apply an approved thread sealant or PTFE tape rated for the service medium before making up the joint. Do not over-tighten threaded connections, as this can crack cast fittings or distort threads.
