1 inch Copper Coupling less Stop Copper x Copper

1 inch Copper Coupling with Stop – Built for Seamless Sweat Connections

The 1 inch Copper Coupling with Stop is manufactured for sweat (soldered) applications, providing a secure and permanent joint between two copper pipes of the same diameter. Featuring an internal stop, this fitting ensures precise alignment during installation, allowing for even heat distribution and proper solder flow.

Engineered for System Longevity

• ✅ Material Grade: Lead-free wrought copper per ASTM B75/B88 standards for potable water systems.
• ✅ Stop Design: Center stop helps position the pipes accurately for consistent insertion depth and optimal joint strength.
• ✅ Reliable in High-Pressure Systems: Suitable for residential and commercial use in water supply, hydronic heating, and chilled water lines.
• ✅ Corrosion Resistance: Copper’s natural resistance to scaling and biofouling ensures long-term performance without internal obstruction.

Technical Specifications

• Material: Lead-free copper
• Nominal Size: 1 inch
• Connection Type: Sweat x Sweat with internal stop
• Standard Compliance: Meets NSF 61 and ASME B16.22

Installation Notes

This coupling is intended for soldered joints and requires pipe cleaning, proper flux application, and even heat for reliable bonding. The internal stop ensures alignment and consistent spacing between pipes, minimizing rework. Use of lead-free solder is mandatory for potable applications.

Application Overview

Primarily used in copper piping systems for potable water, this fitting is also suitable for HVAC lines, refrigeration, and other mechanical systems where copper tube is specified. Its consistent wall thickness and smooth internal bore contribute to efficient flow and system integrity.

Did You Know?

Wrought copper fittings are preferred for their higher pressure ratings compared to cast alternatives, particularly in systems where reliability under thermal cycling is critical.

The 1 inch Copper Coupling with Stop delivers dependable joint integrity, ease of alignment, and compliance with current code requirements. It’s an essential component for professional-grade installations in pressurized copper systems.
