The PAPC0403 is a high-quality reducing coupling designed to connect 3/4-inch and 1/2-inch PEX tubing in water distribution systems. Made from durable poly alloy (engineered polymer), this fitting offers a lightweight, corrosion-resistant alternative to brass, ideal for both residential and commercial plumbing applications.

Key Features:

• Reducing Barb Design: Features one 3/4-inch and one 1/2-inch PEX barb connection, allowing for seamless transitions between different pipe sizes in PEX systems.
• Durable Poly Alloy Construction: Engineered from high-strength polymer, this coupling resists corrosion, scale buildup, and chemical degradation, ensuring long-term reliability in both hot and cold water applications.
• PEX System Compatibility: Designed for use with PEX tubing and compatible with copper crimp rings or stainless steel clamp (cinch) systems.
• Lead-Free & Potable Water Safe: Certified for use in potable water systems, meeting NSF/ANSI 14, 61, and 372 standards
• Temperature & Pressure Ratings:
  • Maximum Pressure: 100 PSI
  • Maximum Temperature: 180°F
• Compact & Lightweight: Ideal for installations in tight spaces, with no need for soldering or adhesives.

Applications:

• Residential and commercial potable water systems
• Hydronic and radiant heating installations
• Plumbing retrofits and new construction
• Transitioning between 3/4 in. and 1/2 in. PEX lines
