Value Collection 41/2SPU21/2 Ss Half Coupling Npt

Product Description

The VALUE COLLECTION 41/2SPU21/2 is a stainless steel half coupling designed for threaded pipe assembly using NPT (National Pipe Taper) connections. Half couplings are used to branch off a pipe run or cap a pipe end with a threaded female port, and they are a standard component in plumbing, HVAC piping systems, and industrial fluid handling. This fitting ships as a single unit and is constructed from stainless steel for corrosion resistance in demanding service environments. Plumbers, pipefitters, and mechanical contractors regularly specify half couplings for both new construction and retrofit piping work.

This half coupling is suited for residential and commercial plumbing and piping applications where a durable, corrosion-resistant threaded fitting is required. NPT threading makes it compatible with standard pipe thread assemblies found in water supply, steam, and process piping systems. Its compact profile allows installation in tight spaces where a full coupling would not fit. The single-piece package quantity makes it easy to order exactly the quantity needed for a specific job.

Key Features

• Stainless steel construction resists corrosion in wet, steam, and chemical-adjacent service conditions
• NPT (National Pipe Taper) end connection for leak-resistant threaded assembly with standard pipe
• Half coupling design provides a single threaded female port for branch connections or pipe terminations
• Compact dimensions suited for installations with limited clearance
• Sold individually for precise quantity sourcing

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded pipe systems in plumbing and mechanical piping applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the affected pipe system before beginning work. Apply an appropriate thread sealant or PTFE tape to NPT threads before assembly to ensure a pressure-tight joint. Do not overtighten threaded connections, as stainless steel fittings can gall if excessive force is applied.
