1 inch Brass Press Union Press x Press

1 Inch Brass Press Union – Press x Press Connection for Potable Water and Hydronic Systems

The 1 inch Brass Press Union (Press x Press) provides a flame-free connection method for joining copper tubing systems. Designed for use in potable water distribution and hydronic heating applications, this fitting offers dependable performance and ease of installation using standard press tools.

Material and Manufacturing Integrity

This union is produced from lead-free brass in compliance with potable water codes and is designed to deliver repeatable joint integrity under fluctuating pressure and temperature conditions:

• ✅ Machined Press Ends Ensure uniform contact with copper tubing for consistent joint compression.
• ✅ Lead-Free Alloy Complies with NSF/ANSI 61 and NSF/ANSI 372 for use in potable water systems.
• ✅ Corrosion Resistance Brass construction provides long-term durability in domestic and light commercial water systems.

Installation Considerations

Intended for use with compatible copper tubing and press-fitting systems. Proper preparation of tubing ends—including cleaning and depth marking—is critical for sealing reliability. Use of calibrated press tools and jaws appropriate to the fitting size is required.

• ✅ Pipe Preparation Cut copper tubing square and deburr prior to pressing.
• ✅ Press Equipment Utilize tools and jaws listed as compatible by the fitting manufacturer.
• ✅ No Flame Required Allows for safe installation in enclosed or occupied spaces without hot work permits.

Application Scope

This press union fitting is suitable for use in systems conveying potable water, closed-loop hydronic heating, and non-potable water distribution where copper tube is used. The union configuration allows for disassembly and section replacement without disturbing adjacent connections.
