Corrosion-resistant 304 stainless steel crimp rings for making permanent, watertight connections between PEX tubing and ASTM F1807 brass crimp fittings. Stainless construction outperforms copper rings in freeze resistance and long-term corrosion durability.

• 304 stainless steel resists corrosion, chlorine attack, and freeze expansion
• Meets ASTM F1807 for use with brass PEX crimp fittings
• Compatible with PEX-A, PEX-B, and PEX-C tubing at 1/2"
• Creates a 360-degree watertight seal when properly crimped
• System rated to 160 PSI at 73F and 100 PSI at 180F
• Requires standard PEX crimp tool for installation
• 10 rings per bag

Tip: After crimping, verify the ring falls within the go/no-go gauge tolerance -- a rejected crimp means the ring is not fully seated and the joint may leak.
