COPPER TUBING ROLL GROOVE SPECIFICATIONS
COLUMN 1 - Nominal ASTM B-88 drawn copper tubing size
COLUMN 2 - Outside diameter: The outside diameter of roll grooved tubing shall not vary more than the
tolerance listed. The maximum allowable tolerance from square cut ends is 0.030" (0.8 mm) for 2 - 3" (50 - 80 mm);
0.045" (1.1 mm) for 4 - 6" (100 -150 mm), measured from true square line.
COLUMN 3 - Gasket seat: The tubing surface shall be free from indentations, roll marks, and projections from
the end of the tubing to the groove, to provide a leak-tight seat for the gasket. All loose scales, dirt, chips and
grease must be removed.
COLUMN 4 - Groove width: Bottom of groove to be free of loose dirt, chips and scale that may interfere with
proper coupling assembly.
COLUMN 5 - Groove outside diameter: The groove must be uniform depth for the entire tubing circumference.
Groove must be maintained within the "C" diameter tolerance listed.
COLUMN 6 - Groove depth: For reference only. Groove must conform to the groove diameter "C" listed.
COLUMN 7 - ASTM B-306 drain waste and vent (DWV) is minimum wall thickness copper tubing which may be
roll grooved.
COLUMN 8 - Maximum allowable end flare diameter: measured at the most extreme tubing end diameter.
