a. The maximum cold water pressure for general piping services tested to ASTM F1476 and/or AWWA C606 methods. Figures listed are based on roll-grooved Type K-ASTM B-88 copper Tubing. For more information on other types, contact GRINNELL Technical Services.
• Couplings with rubber gaskets are likely to function as an insulator. Where electrical continuity is required, GRINNELL Continuity Clip will restore electrical continuity to the system. The continuity clip satisfies IEE Wiring Regulations.
• Refer to Tech Data Sheet G511 Figure 616 Reducing Coupling for Joining Copper Tubing Systems.
