Viega 35020 Pex-al-pex Tubing 0.5 Inch 150 Foot Coil

Product Description

The VIEGA 35020 is a 1/2-inch PEX-AL-PEX composite tubing supplied in a 150-foot coil, engineered for radiant heating and hydronic distribution systems. The construction bonds a cross-linked polyethylene core to an aluminum layer and a PE outer jacket, providing an integral oxygen barrier and excellent form stability. Rated to 160 psi and 200 degrees F, this tubing handles the pressure and temperature demands of residential and light-commercial heating applications. The aluminum layer allows the tubing to be bent by hand and hold its shape without a support fitting, making it a practical choice for exposed basement runs and baseboard connections. A licensed plumber or radiant heating installer is the typical trade professional for this product.

VIEGA 35020 is designed for hydronic heating installations including radiant floor systems, baseboard heating loops, and mechanical room distribution manifolds. Its gray color and rigid-hold bend characteristic make it well-suited for exposed interior runs where neat, self-supporting routing is required. The tubing is compatible with Viega press fittings only and must not be used with crimp, clamp, or expansion-style PEX fittings. It meets NSF, ASTM F876, and ASTM F877 standards, confirming suitability for potable and heating system use where those certifications are required by local code.

Key Features

• PEX-AL-PEX three-layer construction provides a built-in oxygen barrier, reducing system corrosion in closed hydronic loops
• Retains bent shape without support fittings, ideal for exposed basement and baseboard runs
• Rated to 160 psi and 200 degrees F for demanding hydronic heating service
• Compatible with Viega press fittings only — not for use with crimp, clamp, or expansion tooling
• Meets NSF, ASTM F876, and ASTM F877 standards
• Supplied in a 150-foot coil for efficient handling on the job site

Compatibility

Designed for use with Viega press fittings only. This tubing is not compatible with crimp-ring, clamp, or expansion-style PEX fittings. Intended for radiant and hydronic heating system applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified hydronic heating technician in accordance with local plumbing and mechanical codes. Shut off and depressurize the system before cutting or connecting tubing. Use only Viega-approved press tooling and fittings — substituting other fitting types will void compatibility and may compromise system integrity. Minimum bend radius should be observed to avoid kinking; the aluminum layer holds bends but will not recover from a kink.
