The Value Collection 6CU-TFF3 is a stainless steel union pipe fitting designed to create a removable, leak-tight connection in pressurized piping systems. Unions allow technicians to disconnect and reconnect pipe runs without cutting or threading additional pipe, making them essential for serviceable installations. This fitting features NPT (National Pipe Taper) threaded end connections and is constructed from stainless steel for corrosion resistance in demanding environments. At 4.31 pounds, it is a solid, heavy-duty fitting suited for professional plumbing, HVAC hydronic, and industrial piping applications.
This union fitting is appropriate for residential and commercial plumbing and mechanical systems where periodic service access is required. It is commonly installed in boiler rooms, mechanical rooms, and process piping runs where lines must be broken for equipment maintenance or replacement. Licensed plumbers and pipefitters typically install union fittings of this type in both new construction and retrofit work.
Designed as an OEM-style replacement or direct-install union fitting for standard NPT-threaded stainless steel piping systems.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local mechanical codes. Shut off and depressurize the system completely and allow lines to cool before disassembling or installing any pipe fitting. Apply an appropriate thread sealant or PTFE tape to NPT threads before assembly and tighten to a secure, snug fit without over-torquing. Inspect the union seat and nut after pressurizing the system to confirm a leak-free connection.
