Value Collection 4CU-TFF3 Stainless Steel Union Npt

Product Description

The VALUE COLLECTION 4CU-TFF3 is a stainless steel union pipe fitting designed for threaded piping systems. A union allows two sections of pipe to be connected or disconnected without rotating either section, making it a practical choice for systems that require periodic service or component replacement. The NPT (National Pipe Taper) end connections provide a pressure-rated threaded seal standard across plumbing, HVAC, and industrial piping installations. This fitting weighs 4.31 pounds and measures approximately 4.75 inches wide and 3.5 inches in height. It is sold as a single unit and is installed by licensed plumbers and pipefitters.

This union fitting is suited for residential and commercial piping applications where stainless steel corrosion resistance is required. Common installation scenarios include hydronic heating systems, process piping, chemical-compatible fluid lines, and general plumbing where NPT-threaded connections are specified. The stainless steel construction makes it appropriate for environments exposed to moisture, mild chemicals, or elevated temperatures where carbon steel fittings would be unsuitable.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing codes. Shut off and fully depressurize the piping system before disassembling or installing any union fitting. Apply an appropriate thread sealant or PTFE tape to NPT threads before assembly to ensure a leak-free joint. Do not overtighten threaded connections, as this can crack fittings or damage threads.
