3/4 inch Copper Coupling Less Stop Copper x Copper (Pack of 25)

3/4 Inch Copper Coupling – Less Stop, Copper x Copper (25-Pack)

This 3/4 inch Copper Coupling (less stop) is engineered for joining two lengths of copper tubing in continuous line applications where no internal stop is required. Manufactured to meet industry standards for sweat fittings, this component supports soldered connections in pressure and non-pressure piping systems.

Product Advantages for Contractors

Designed for efficient field use, this coupling supports precise installations and consistent performance across varied piping layouts. Key attributes include:

• ✅ Uniform Machining Precision-formed for consistent wall thickness and dimensional accuracy, allowing tight capillary fit for soldering.
• ✅ Lead-Free Alloy Complies with NSF/ANSI 61 and 372 standards for use in potable water systems across all jurisdictions.
• ✅ Stop-Less Design Open bore allows slip-on access from either end, ideal for continuous lines and repair sections.
• ✅ High-Temperature Tolerance Suitable for brazing or soldering using standard flux and filler materials, maintaining mechanical integrity under thermal load.
• ✅ Streamlined Installation Chamfered edges and clean internal surfaces promote better solder flow and reduce prep time on-site.

Installation Guidance

Designed for use with ASTM B88 Type L or M copper tubing. Installation requires proper cleaning, fluxing, and soldering using accepted trade practices. Tools typically used include:

• Copper tubing cutter or fine-toothed saw
• Emery cloth or fitting brush for surface prep
• Approved flux and solder
• Propane or MAP-pro torch with heat control

Installers must ensure complete solder penetration at the joint to meet code-compliant seal standards.

Typical Applications

This coupling is widely used in both new construction and retrofit scenarios for domestic water supply, hydronic heating, and low-pressure closed-loop systems. Its less-stop format makes it especially useful in horizontal line extensions or sections requiring precise axial alignment without flow obstruction.

Material and Compliance

• Material: Lead-free copper (compliant with Federal Safe Drinking Water Act requirements)
• Nominal Size: 3/4 inch
• Connection: Copper x Copper (sweat/solder)
• Configuration: Straight coupling, no center stop
• Pack Quantity: 25 units

This coupling meets dimensional and performance criteria required for use in pressure-rated copper systems and is suitable for both residential and light commercial installations where stopless couplings are preferred.
