The Apollo ExpansionPEX™ EPXC341 is a high-quality reducing coupling designed for cold-expansion PEX-A plumbing systems. Made from lead-free, dezincification-resistant brass, this fitting provides a secure, leak-free connection when transitioning between 1″ and 3/4″ PEX-A tubing. Built for durability and compliance, it’s ideal for potable water and hydronic heating applications.

Key Features

• Reducing Coupling Design: Connects 1″ PEX-A tubing to 3/4″ PEX-A tubing for smooth transitions.
• Lead-Free Brass Construction: Safe for potable water systems; corrosion-resistant for long-term reliability.
• Cold-Expansion Compatibility: Designed for PEX-A tubing and expansion rings; requires approved expansion tools.
• High-Performance Rating: Handles up to 200 psi and 200 °F for residential and light commercial systems.
• Code-Compliant: Meets ASTM F1960 and major plumbing standards.

Specifications

• Connection Type: PEX Barb × PEX Barb
• Material: Lead-free brass
• Nominal Size: 1″ × 3/4″
• Maximum Temperature: 200 °F
• Maximum Pressure: 200 psi
