3/8 inch PEX Copper Crimp Ring

3/8 inch Copper Crimp Ring by Viega – Precision-Fit for Secure PEX Installations

The 3/8 inch Copper Crimp Ring from Viega is designed for joining PEX tubing in potable water and hydronic heating systems. Engineered for use with ASTM F1807-style fittings, this ring delivers uniform compression over the pipe and fitting to create a mechanically sound, leak-resistant joint.

Constructed from high-grade copper for corrosion resistance and consistent deformation properties, it supports code-compliant installations across a range of residential and light commercial applications.

Key Functional Benefits

• ✅ Consistent Crimp Profile Designed for compatibility with standard crimp tools, producing uniform and repeatable seals at 3/8 inch diameter.
• ✅ High-Copper Alloy Fabricated from clean copper stock for oxidation resistance and material integrity under pressure.
• ✅ Leak Mitigation Provides 360° contact with PEX and fitting surfaces, ensuring a tight seal without cold flow or creep over time.
• ✅ Standards Compliance Meets ASTM F1807 specifications and is suitable for use in pressure-rated PEX installations requiring third-party verified fittings.
• ✅ Jobsite Efficiency Simplifies installation workflow and reduces rework when installed with calibrated tools and verified system components.

Installation Guidance

Use with approved 3/8 inch PEX tubing and ASTM F1807 brass or polymer fittings. Proper tool calibration is critical for achieving target crimp diameter and preventing leaks. Always verify crimp integrity using a go/no-go gauge as specified by code and manufacturer guidelines. Connections must be made in clean, debris-free conditions to ensure full seating of tubing and rings.

Applications

Typical installations include potable cold and hot water lines, baseboard or radiant heating circuits, and branch manifold configurations. The 3/8 inch size is frequently utilized in low-flow fixtures, localized distribution loops, and compact plumbing systems requiring precision and compact fittings.

Material Consideration

Copper is inherently antimicrobial and resists degradation under varying temperature and pressure conditions. When properly crimped, copper rings offer long-term reliability in both indoor and covered outdoor environments.
