Value Collection 4CU-TFF4 Stainless Steel Union Npt

Product Description

The VALUE COLLECTION 4CU-TFF4 is a stainless steel union pipe fitting designed for threaded pipe systems using NPT (National Pipe Taper) end connections. Unions allow technicians to disconnect and reconnect piping runs without cutting or unthreading an entire line, making them a go-to fitting for servicing pumps, valves, and equipment in fluid and gas systems. Constructed from stainless steel, this fitting resists corrosion in both wet and chemically active environments. It is a standard trade fitting installed by licensed plumbers, pipefitters, and HVAC technicians in commercial and industrial piping applications.

The 4CU-TFF4 is suited for applications where stainless steel construction is required to meet corrosion resistance or sanitary standards. Typical installations include process piping, mechanical rooms, pump stations, and HVAC hydronic systems. The NPT threaded ends provide a standard tapered thread connection compatible with common pipe and fitting stock. This fitting ships as a single unit and is appropriate for both new installation and maintenance replacement work.

Key Features

• Stainless steel construction provides corrosion resistance in wet and chemically active environments
• NPT end connections offer compatibility with standard tapered-thread pipe systems
• Union design allows full disconnection of the piping run without disturbing adjacent fittings
• Single-piece package quantity simplifies per-unit procurement for service calls

Compatibility

Designed as an OEM-style replacement or new-installation union fitting for standard NPT threaded pipe systems requiring stainless steel construction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local mechanical code requirements. Depressurize and drain the system completely before removing or installing any union fitting. Apply an approved pipe thread sealant or PTFE tape to the NPT threads before assembly. Do not overtighten, as stainless steel threads can gall if excessive torque is applied without proper lubrication.
