1 inch PEX Copper Crimp Ring

1" Viega PEX Crimp Ring – Designed for Secure, Code-Compliant Water Connections

The 1" Viega PEX Crimp Ring is a precision-formed metal ring engineered for use with ASTM F1807 brass or polymer PEX insert fittings and PEX tubing. Manufactured to ASTM F1807 and F877 standards, this crimp ring ensures consistent radial compression around the pipe and fitting, resulting in a durable, leak-resistant joint suitable for potable water and hydronic distribution systems.

Constructed from annealed copper for corrosion resistance and strength, this ring provides reliable performance in both hot and cold water applications. The 1" size is compatible with SDR9 PEX tubing and can be installed using any ASTM F1807-compliant crimping tool. It is an essential component in PEX systems requiring a permanent mechanical connection with verified visual inspection capability through standard go/no-go gauges.

Product Features and Application Benefits

• ✅ Material: Annealed copper for high corrosion resistance and mechanical durability
• ✅ Standard Compliance: Meets ASTM F1807, F877, and CSA B137.5 performance criteria
• ✅ Connection Type: PEX-to-fitting mechanical compression using crimping method
• ✅ Installation Verification: Supports use of go/no-go gauges to ensure proper crimp integrity
• ✅ Thermal Stability: Maintains seal in temperature ranges typically from 32°F to 200°F (0°C to 93°C)

Installation Guidelines

To install, slide the ring over the PEX tubing and insert the fitting fully. Position the crimp ring 1/8" to 1/4" from the tubing end, over the fitting barb. Use an approved crimp tool to apply uniform compression. After crimping, verify connection using an appropriate go/no-go gauge. Improper alignment or crimping can compromise the joint integrity, so adherence to manufacturer and code requirements is critical.

Common Use Cases

Viega PEX crimp rings are typically used in residential and commercial potable water systems, hydronic heating, and snow melt applications. The 1" size is often deployed in main trunk lines or high-volume supply runs within a PEX manifold layout.

Code and Certification

This crimp ring is NSF-listed for potable water applications and is lead-free per NSF/ANSI 61 and 372 standards. It is accepted for use in plumbing systems governed by IPC, UPC, and local code jurisdictions.

Professionals rely on ASTM-compliant crimp technology for its proven longevity and mechanical simplicity. The 1" Viega PEX Crimp Ring delivers consistent, repeatable results under field conditions and is an integral part of high-performance PEX installations.
