Value Collection 4CU-CFF3/4 Pipe Union 3/4 in 304 Ss

Product Description

The VALUE COLLECTION 4CU-CFF3/4 is a 3/4-inch threaded pipe union rated for 150 psi service. Constructed from 304 stainless steel, it connects two sections of threaded pipe with female NPT connections on both ends, allowing the line to be broken and reconnected without disturbing the surrounding piping. Plumbers and pipefitters install this fitting in fluid systems where periodic maintenance access or equipment removal is required. The stainless steel construction resists corrosion in wet, chemical-adjacent, and outdoor environments where carbon steel fittings would degrade.

This union is suited for residential and light commercial plumbing, process piping, HVAC hydronic systems, and general industrial fluid lines. The FNPT x FNPT configuration accepts standard NPT-threaded pipe on both sides, making it a direct fit into existing threaded piping runs. It is commonly used at isolation points near pumps, valves, and equipment connections where disassembly is anticipated during the service life of the system.

Key Features

• 304 stainless steel construction resists corrosion and oxidation in wet or chemically active environments
• 150 psi pressure rating suitable for standard service plumbing and hydronic applications
• FNPT x FNPT threaded end connections on both sides for compatibility with standard NPT pipe threads
• Union design allows line break and reassembly without cutting or rethreading pipe
• 3/4-inch fitting size fits common pipe runs in residential and light commercial systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch NPT threaded pipe systems rated at 150 psi or below.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before removing any existing fitting or installing this union. Apply thread sealant tape or pipe dope rated for the service fluid to all male threads before assembly. Do not over-tighten threaded connections; use a pipe wrench with appropriate leverage for the fitting size and inspect for leaks after restoring pressure.
