1/4 inch Copper Coupling with Stop Copper x Copper

1/4 inch Copper Coupling with Stop – Sweat Fitting for Precision Line Extension

The 1/4 inch Copper Coupling with Stop is a solder-type fitting used to join two sections of copper tubing in a straight alignment. Designed with an internal stop to center pipe ends during assembly, it ensures accurate positioning and uniform solder distribution across the joint.

Fabricated from lead-free wrought copper, this coupling is suitable for use in potable water systems, HVAC installations, and low-pressure process piping. Its compact size and standardized dimensions make it ideal for applications requiring precise spacing and minimal profile.

Performance Characteristics

Engineered to meet professional installation standards, this coupling provides dependable performance under routine service conditions:

• ✅ Formed Center Stop – Ensures proper pipe insertion depth and maintains alignment during joining.
• ✅ Sweat Connections – Designed for soldered joints using lead-free solder and compatible fluxes.
• ✅ Code-Compliant – Manufactured to meet NSF/ANSI and ASME requirements for potable systems.
• ✅ Corrosion Resistant – Copper alloy resists internal and external corrosion in water supply environments.
• ✅ Consistent Wall Thickness – Promotes even heat transfer for strong, leak-resistant joints.

Technical Specifications

• Material: Lead-Free Wrought Copper
• Nominal Size: 1/4 inch
• Connection Type: Copper x Copper (Sweat x Sweat with Stop)
• Standards Compliance: ASME B16.22, NSF/ANSI 61 & 372

Installation Notes

This fitting is designed for soldering. Surfaces must be properly cleaned and fluxed prior to assembly. Heat should be applied evenly to allow full solder flow into the capillary joint. Allow sufficient cooling before pressurizing the system. Not designed for use in press-fit, flare, or compression systems unless otherwise specified by the product variant.

Application Scope

Typically installed in water distribution lines, hydronic heating circuits, refrigeration tubing, and general mechanical piping systems. The 1/4 inch size is commonly used in equipment connections, instrumentation loops, and areas requiring precision alignment in small-diameter tubing.

Regulatory Note

All fittings used in drinking water systems must conform to lead-free regulations under the Safe Drinking Water Act (SDWA). This coupling is fully certified and marked for compliance verification.
