Value Collection 41/2SPU2 Half Coupling Npt Stainless Steel

Product Description

The Value Collection 41/2SPU2 is a stainless steel half coupling designed for threaded pipe connections in plumbing, industrial, and mechanical piping systems. A half coupling features threading on one end only, allowing a branch connection or end cap fitting to be welded or threaded into a pipe run. The NPT (National Pipe Taper) end connection provides a pressure-rated threaded seal standard across North American trade work. This fitting is suited for water, steam, and compatible fluid service lines where corrosion resistance is a priority.

This half coupling is used in residential and commercial piping installations requiring a stainless steel fitting at a threaded branch or pipe termination point. Typical applications include process piping, utility plumbing, and HVAC hydronic systems where NPT-threaded stainless fittings are specified. It is sold individually and is appropriate for new construction or repair work where a single fitting is needed to complete a connection.

Key Features

• Stainless steel construction provides corrosion resistance in wet and chemically active environments
• NPT end connection delivers a standard tapered thread seal compatible with common pipe stock
• Half coupling configuration allows single-end threaded branch connections
• Compact form factor suits tight-clearance installations
• Sold as a single unit for targeted repair or new-installation use

Compatibility

Designed as an OEM-style replacement or new-installation fitting for NPT-threaded stainless steel pipe systems in plumbing, HVAC, and industrial piping applications.

Installation Notes

Installation of threaded pipe fittings should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ANSI standards. Shut off and depressurize the line before beginning work. Apply an appropriate thread sealant or PTFE tape to the NPT threads prior to assembly. Do not overtighten, as stainless steel threads can gall under excessive torque.
