1 Inch Bronze Pack Joint Union – Threaded Connection for Copper Service Lines

The 1 inch Bronze Pack Joint Union provides a reliable, mechanical connection between copper tubing and threaded system components. Designed for use in water service applications, this union allows for disassembly and reassembly of piping without disturbing the tubing. The pack joint configuration accommodates minor misalignment and thermal expansion while maintaining a watertight seal.

Material and Performance Standards

Manufactured from lead-free bronze in compliance with ANSI and NSF requirements, this union is engineered for compatibility with CTS (Copper Tube Size) pipe. The component supports repeated use and is suitable for both above-ground and below-grade installations where access or maintenance is required.

• ✅ Material: Lead-free bronze, compliant with NSF/ANSI 61 and 372
• ✅ Nominal Size: 1 inch CTS inlet x 1 inch FNPT outlet
• ✅ Pressure Rating: Typically up to 175 PSI, depending on system design
• ✅ Temperature Range: Operating range up to 180°F for water service

Application and Use

This fitting is used to join copper tubing to threaded distribution piping in potable water systems. It is commonly installed at meter settings, curb stops, or service entrances. The union design facilitates field service and component replacement without cutting the main line.

Installation Guidelines

The pack joint end uses a compression-style gasket or insert sleeve to form a mechanical seal around CTS copper. The threaded end connects to standard FNPT female threads. Pipe ends must be clean and properly aligned prior to assembly. Apply appropriate thread sealant or PTFE tape to the threaded joint. Do not overtighten to avoid damage to sealing components.

• ✅ Tool Requirements: Standard pipe wrenches for assembly; no flame required
• ✅ Field Maintenance: Can be disassembled and reinstalled without removing tubing
• ✅ Alignment Tolerance: Pack joint design permits minor flexibility in tubing orientation

Certifications and Compliance

• Lead-Free Certification: Meets requirements of the U.S. Safe Drinking Water Act
• NSF Certification: Certified to NSF/ANSI 61 and NSF/ANSI 372 for potable water use
• UPC Listing: Complies with Uniform Plumbing Code installation guidelines

For service line applications requiring a dependable union between copper tubing and threaded connections, the 1 inch Bronze Pack Joint Union offers mechanical strength, reusability, and code compliance. Designed for utility-grade and municipal water systems, this fitting ensures a long-lasting, corrosion-resistant joint under standard operating conditions.
