3/4 inch Bronze Pack Joint Coupling Copper x Copper

3/4" Lead-Free Pack Joint Coupling CTS – For Code-Compliant Copper Tube Connections

The 3/4" Lead-Free Pack Joint Coupling is a compression-style fitting designed for use with CTS (Copper Tube Size) piping in potable water distribution systems. Manufactured from lead-free brass, this coupling is intended for use in municipal and private water service applications requiring a mechanical connection without soldering or flaring.

Pack joint couplings utilize a compression nut and internal sealing ferrule to form a watertight joint. The design is suitable for underground and above-ground installations where serviceability and alignment tolerance are critical. The fitting is compliant with applicable NSF/ANSI standards for materials in contact with drinking water.

• ✅ Mechanical Compression Design – Eliminates the need for heat or solvents; accommodates slight pipe misalignment.
• ✅ Lead-Free Brass Construction – Certified for use in potable water systems and meets regulatory requirements for lead content.
• ✅ Service Line Compatibility – Suitable for connecting copper tubing in residential, commercial, and utility water service installations.

Technical Specifications

• Nominal Size: 3/4"
• Connection Type: Pack Joint (CTS)
• Material: Lead-Free Brass
• Certifications: NSF/ANSI 61 and 372
• Application: Potable Water Service Line Connections

Installation Overview

This fitting is assembled by inserting copper tubing into the coupling body and tightening the compression nut to specification. It requires no flame, solder, or specialty tooling, and can be installed using standard wrenches. Proper surface preparation of the tubing and attention to insertion depth are essential for achieving a pressure-tight seal.

Typical Applications

Used extensively in curb stop-to-meter settings, municipal service lines, and retrofit applications where copper CTS pipe is installed. The coupling is suitable for use in both buried and exposed locations, provided it is protected from excessive mechanical stress.

Regulatory Compliance

In compliance with the 2014 amendments to the Safe Drinking Water Act, this coupling meets all federal requirements for lead content in drinking water components and is certified accordingly.

The 3/4" Lead-Free Pack Joint Coupling CTS provides a durable, field-serviceable solution for copper tube connections in potable water systems. Its mechanical design simplifies installation while ensuring long-term performance under standard operating conditions.
