Value Collection 41/2SPU4 Ss Half Coupling Npt

Product Description

The VALUE COLLECTION 41/2SPU4 is a stainless steel half coupling designed for threaded pipe assemblies in plumbing, industrial, and mechanical systems. A half coupling provides a socket connection on one end only, allowing a pipe or nipple to be threaded in without a matching female fitting on the opposite side. The NPT (National Pipe Taper) end connection ensures a pressure-tight seal when installed correctly with thread sealant or tape. This fitting is suited for licensed plumbers, pipefitters, and mechanical contractors working on fluid-handling and process piping systems.

Half couplings in stainless steel are commonly used in residential and commercial plumbing, HVAC hydronic lines, and light industrial piping where corrosion resistance is required. The NPT threading makes this fitting compatible with standard tapered pipe thread systems widely used across North American trade applications. It is typically installed in low- to medium-pressure fluid or gas piping configurations where a branch connection or pipe extension is needed.

Key Features

• Stainless steel construction for corrosion resistance in wet and chemical environments
• NPT tapered thread end connection for a pressure-sealing fit
• Half coupling design allows single-end pipe or nipple connection
• Compact form factor suitable for tight installation spaces
• Sold individually (package quantity of 1)

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 IPC or local mechanical codes. Shut off and depressurize the supply line before fitting installation. Apply thread sealant tape or pipe dope to the male NPT threads before engagement to ensure a leak-free connection. Do not overtighten; hand-tighten first, then finish with a pipe wrench to the appropriate number of turns past hand-tight per the fitting size.
