Capitol Manufacturing 12204013X Threaded Union 1-1/4 Inch

Product Description

The CAPITOL MANUFACTURING 12204013X is a 1-1/4 inch threaded union fitting designed for joining sections of pipe in plumbing and mechanical piping systems. Threaded unions allow for clean disconnection and reconnection of pipe runs without cutting, making them a standard choice for service points, equipment isolation, and branch connections. This fitting is sold as a single unit and is installed by licensed plumbers and pipefitters working on residential and light commercial systems.

This threaded union is suited for applications where future serviceability is a priority. Typical installation scenarios include water supply lines, boiler piping, and mechanical room connections where equipment may require periodic removal or replacement. The 1-1/4 inch size fits standard NPT-threaded pipe of the same nominal diameter.

Key Features

• 1-1/4 inch nominal size for compatibility with standard NPT-threaded pipe
• Union design allows pipe disconnection without cutting or unthreading long runs
• Sold as a single unit
• Suitable for service-point and equipment-isolation applications

Compatibility

Designed as an OEM-style replacement or direct-fit threaded union for standard 1-1/4 inch NPT piping systems in residential and commercial plumbing and mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the water or fluid supply before beginning work. Apply appropriate thread sealant or PTFE tape to all threaded connections before assembly. Do not overtighten the union nut, as this can damage the seat and cause leaks.
