COPPER TUBING ROLL SPECIFICATIONS NOTES
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" (60.3 - 88.9 mm); 0.045" (1.1 mm) for 4 - 6"
(114.3 - 168.3 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 scale, 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 as-
sembly.
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 dia.
