Value Collection BD--13688-9 Black Pipe Nipple Sch 80

Product Description

The VALUE COLLECTION BD--13688-9 is a Schedule 80 black steel pipe nipple used to connect threaded pipe runs in plumbing, HVAC, gas distribution, and industrial piping systems. It measures 1-1/4 inches in diameter and 10-1/2 inches in length, with male NPT threads on both ends. The welded steel construction and black finish coating make it suitable for low-pressure steam, water, gas, and air applications. Licensed plumbers, pipefitters, and HVAC technicians install this nipple as a close-coupled extension between fittings, valves, or equipment connections.

This nipple fits standard 1-1/4 inches NPT threaded systems and is appropriate for residential and light commercial piping applications. It is commonly used in boiler piping, gas line extensions, compressed air distribution, and water supply rough-in work where a heavier wall thickness is required. Schedule 80 wall thickness provides additional strength compared to Schedule 40, making it preferred in higher-pressure or higher-stress installations.

Key Features

• Schedule 80 wall thickness for added strength in demanding piping applications
• Welded steel construction for consistent dimensional integrity
• Black finish coating standard for gas and steam service identification
• Male NPT threads on both ends for direct connection to standard fittings and valves
• 1-1/4 inches pipe size with 1-1/4 to 11-1/2 thread specification

Compatibility

Designed as a standard replacement or new-installation nipple for 1-1/4 inches MNPT x MNPT Schedule 80 threaded black steel piping systems in plumbing, HVAC, and gas distribution applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable codes such as the IPC or IFGC depending on the service medium. Shut off and depressurize the line before removing or installing any threaded components. Apply listed thread sealant or PTFE tape appropriate for the service type before threading the nipple into fittings. Hand-tighten first, then use a pipe wrench to achieve a leak-free joint without over-stressing the fitting threads.
