Curtis NIPPLE11/4X7 Black Pipe Nipple 1.25x7 Sch 40

Product Description

The CURTIS NIPPLE11/4X7 is a Schedule 40 black steel pipe nipple sized at 1.25 inches nominal diameter by 7 inches in length. Pipe nipples are short threaded sections used to connect two female-threaded fittings, valves, or equipment ports in a piping run. This nipple is manufactured from black steel, making it suitable for gas, steam, and general industrial piping systems. Licensed plumbers and pipefitters install this type of fitting as part of new construction, repair, or modification of piping systems that require a rigid, durable metal connector between two points.

This nipple is a standard fitting used in residential and commercial applications including natural gas supply lines, propane systems, steam heating systems, and general industrial piping. The 1.25-inch nominal size is common in main gas supply runs and branch lines where moderate flow capacity is required. The 7-inch length provides enough thread engagement and clearance for typical close-quarter connections between fittings, valves, and equipment.

Key Features

• Schedule 40 wall thickness for standard-pressure piping applications
• Black steel construction suited for gas, steam, and industrial service
• 1.25-inch nominal diameter for use in moderate-flow supply runs
• 7-inch overall length provides clearance for typical fitting connections
• Threaded on both ends for connection to female-threaded fittings or valves

Compatibility

Designed as a standard replacement or new-installation pipe nipple for Schedule 40 black iron piping systems using 1.25-inch nominal NPT-threaded fittings and valves.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) depending on the service. Shut off and depressurize the piping system completely before removing or installing any threaded fitting. Apply a listed pipe thread sealant or PTFE tape rated for the intended service to all threaded connections. Never overtighten threaded fittings; use a pipe wrench with proper backup on adjacent fittings to avoid stress on connected equipment.
