Fitting Stopper

Stopper with set insertion depth
6 mm for tubes with 13 or 12 mm Ø
11 mm for tubes with 16 mm Ø

Depth is shown with a marking
The insertion depth is based on the connection depth for Alphacool Hard-Tube connectors, so this measurement does not need to be added when calculating dimensions. If you are not using Alphacool connectors, use the straight mandrel with stylus stopper or calculate the difference using your connectors.

All bending mandrels and stoppers are designed for tube diameters of 12 or 13 mm and 16 mm.
