NOTES:
(1) Gruvlok Coupling and Gruvlok Flange size are identifed by nominal tubing size.
(2) Nominal tube wall thickness.
(3) Maximum line pressure, including surge, to which joint shall be subjected. Working pressure ratings are based on the specifed copper tubing roll grooved per
Gruvlok Copper Method Copper-Prep Specifcations.
NOTE:
For one time feld test only. The maximum joint working pressure may be increased to 1
1
/
2
times the fgure shown.
(4) Maximum end load from all internal and/or external forces, to which the joint shall be subjected.
