The PAPC0303 is a high-quality 1/2-inch PEX coupling designed to connect two sections of PEX tubing in potable water and hydronic heating systems. Made from durable poly alloy (engineered polymer), this fitting offers a corrosion-resistant, lead-free alternative to brass, making it ideal for both residential and commercial plumbing applications.

Key Features:

• Dual 1/2 in. PEX Barb Connections: Designed for joining two 1/2-inch PEX pipes using standard copper crimp rings or stainless steel clamp (cinch) rings, ensuring a secure, leak-resistant seal.
• Durable Poly Alloy Construction: Manufactured from high-strength engineered polymer (polysulfone or PPSU), this coupling resists corrosion, scale buildup, and chemical degradation, ensuring long-term performance in both hot and cold water systems.
• Lead-Free & Potable Water Safe: Certified to meet NSF/ANSI 14, 61, and 372 standards, making it safe for use in drinking water systems.
• High Temperature & Pressure Ratings:
  • Maximum Pressure: 200 PSI
  • Maximum Temperature: 200°F
• Lightweight & Easy to Install: Ideal for tight spaces and overhead applications, with no need for soldering, glue, or special tools beyond standard PEX crimp or clamp tools.
• Cost-Effective Alternative: Offers a more economical solution compared to brass fittings, especially in areas with aggressive water conditions that may corrode metal.

Applications:

• Residential and commercial potable water systems
• Radiant and hydronic heating systems
• Plumbing retrofits and new construction
• PEX line extensions and repairs
