Value Collection Ldhff 15-NPT-3000 Pipe Union 1/2 in

Product Description

The VALUE COLLECTION LDHFF 15-NPT-3000 is a 1/2 inch threaded pipe union rated for 3,000 psi service in demanding fluid and gas piping systems. Constructed from 316 and 316L stainless steel, this fitting delivers strong corrosion resistance in aggressive media environments including chemical, marine, and high-moisture applications. The female NPT x female NPT (FNPT x FNPT) end connections allow inline union assembly using standard threaded pipe. Plumbers, pipefitters, and industrial maintenance technicians install this type of fitting where a line must be broken and reconnected during service or equipment changeout.

This union is suited for residential and commercial plumbing, process piping, and industrial fluid systems where stainless steel construction and high-pressure capability are required. The 3,000 psi pressure rating supports use in hydraulic, steam, and high-pressure water lines within the fitting's rated range. The 316 and 316L dual-grade material certification makes it appropriate for both standard and low-carbon weld-adjacent applications, though this fitting is threaded, not welded.

Key Features

• 3,000 psi pressure rating for high-pressure piping service
• 316 and 316L stainless steel construction for corrosion resistance in aggressive environments
• FNPT x FNPT threaded end connections for standard pipe assembly
• 1/2 inch fitting size for common small-bore pipe runs
• Union design allows disconnection and reconnection of piping without cutting

Compatibility

Designed as a threaded union replacement or new-installation fitting for 1/2 inch NPT piping systems requiring 316 or 316L stainless steel construction at up to 3,000 psi.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable piping codes such as the IPC or ASME B31 standards. Depressurize and drain the line completely before breaking or assembling any union connection. Apply appropriate thread sealant or PTFE tape to the male threads mating into this fitting, following the sealant manufacturer's guidance for the service media. Do not exceed the 3,000 psi pressure rating of this fitting.
