Value Collection Ldhff 40-NPT-3000 Pipe Union 1-1/2 in

Product Description

The VALUE COLLECTION LDHFF 40-NPT-3000 is a 1-1/2 inch threaded pipe union constructed from 304 and 304L stainless steel. It connects two sections of pipe with female NPT threads on both ends, allowing for easy disassembly without rotating either pipe run. Rated to 3,000 psi, this union is built for high-pressure service in demanding industrial and commercial plumbing systems. Plumbers and pipefitters install this fitting where maintenance access or future removal of a pipe segment is required. The 304 and 304L dual-grade material provides corrosion resistance suitable for a wide range of fluid service applications.

This pipe union is used in industrial piping systems, commercial plumbing installations, and process fluid lines where high-pressure-rated stainless steel fittings are specified. The FNPT x FNPT end connections are compatible with standard NPT-threaded pipe and fittings at 1-1/2 inches. Typical installation scenarios include mechanical rooms, process piping runs, and equipment isolation points where union access is needed for servicing inline components. It is appropriate for both new construction and retrofit applications requiring a durable, corrosion-resistant union at high working pressures.

Key Features

• 1-1/2 inch fitting size for standard NPT pipe runs
• Union design allows pipe disassembly without rotating adjacent pipe sections
• Weighs approximately 5.51 pounds

Compatibility

Designed as a replacement or new-installation union for 1-1/2 inch NPT-threaded stainless steel pipe systems rated to 3,000 psi.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter in accordance with applicable codes such as the IPC or relevant industrial piping standards. Depressurize and drain the line completely before removing or installing the union. Apply an appropriate thread sealant rated for the service fluid and pressure before assembly. Do not overtighten threaded connections, and ensure the union nut seats squarely to prevent leaks at the union face.
