1/2 inch Copper Coupling Less Stop Copper x Copper (Pack of 25)

1/2 inch Copper Coupling – Full Flow, Less Stop, Copper x Copper (25-Pack)

The 1/2 inch Copper Coupling (Less Stop) is a straight, full-flow fitting designed for joining two lengths of Type K, L, or M copper tubing. Manufactured from lead-free wrot copper, this coupling allows continuous pipe insertion without a center stop, making it suitable for inline splicing or offset realignment in soldered copper piping systems.

Product Features

• Less-Stop Configuration: No internal ridge—allows insertion from either end for full-length inline joins.
• Wrot Copper Construction: Lead-free material compliant with NSF/ANSI 61 and 372 for potable water use.
• Sweat Connection: Socket x Socket design for soldered joints using standard copper tube.
• Dimensional Accuracy: Machined to tight tolerances for reliable insertion depth and solder flow.
• Pack Size: 25 couplings per carton for jobsite readiness.

Technical Specifications

• Nominal Size: 1/2 inch
• Connection: Copper x Copper (sweat ends)
• Material: Lead-free wrot copper
• Standards: ASME B16.22, ASTM B75, NSF/ANSI 61 and 372
• Application: Potable water systems, hydronic heating, and general-purpose soldered copper installations

Installation Guidelines

Install using approved soldering techniques. Pipe ends must be reamed and cleaned prior to assembly. Apply flux to both mating surfaces and use lead-free solder per applicable code. Ensure full socket insertion for structural integrity and flow consistency. Couplings should not be used in press-connect systems unless specifically rated.

Application Use Cases

Common in new construction and retrofit plumbing installations, this fitting is used in:

• Domestic water supply lines (hot and cold)
• Closed-loop hydronic heating systems
• Branch line repairs or extensions
• Offset realignments in copper trunk lines

Compliance Note

All 50 U.S. states require the use of lead-free components in potable water systems. This coupling meets those standards and is suitable for use in code-compliant plumbing assemblies.

The 1/2 inch Copper Coupling (Less Stop) offers a compact, full-flow joining solution for professional soldered copper piping systems. Its precision-formed design and material reliability support long-term system performance in both residential and commercial environments.
