Value Collection 4CU-CFF1/2 Pipe Union 1/2 in Ss

Product Description

The VALUE COLLECTION 4CU-CFF1/2 is a 1/2 inch threaded pipe union rated for 150 psi service. Constructed from 304 stainless steel, it connects two sections of pipe with female NPT threads on both ends, allowing the joint to be broken and reassembled without disturbing the rest of the run. This type of fitting is a standard component in plumbing, HVAC hydronic piping, and light industrial fluid systems where periodic disassembly for service or component replacement is required. Licensed plumbers and pipefitters install these fittings in water supply, chemical transfer, and process piping applications.

This union is suited for residential and light commercial installations where a removable threaded connection is needed in a stainless steel line. The FNPT x FNPT configuration makes it compatible with standard NPT-threaded pipe and fittings in 1/2 inch nominal size. It is commonly used in corrosion-resistant piping systems handling water, mild chemicals, or other compatible fluids at or below the rated pressure.

Key Features

• 304 stainless steel construction resists corrosion in wet and mildly chemical environments
• 150 psi pressure rating suitable for standard plumbing and hydronic applications
• FNPT x FNPT threaded ends for connection to standard 1/2 inch NPT pipe and fittings
• Union design allows line to be broken and rejoined without cutting or disturbing adjacent fittings
• Threaded connection requires no special tooling beyond a pipe wrench and thread sealant

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch NPT threaded piping systems in residential and commercial plumbing, hydronic heating, and light industrial fluid handling.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and the IPC. Shut off and depressurize the system fully before disassembling or installing any threaded union. Apply an appropriate thread sealant compound or PTFE tape to all male NPT threads before assembly. Do not overtighten; snug plus 1 to 2 wrench turns is typical for threaded NPT fittings, and forcing the joint can crack the union nut or distort the seat.
