MAINPRESS pressing system

MAINPRESS pressing system

Dim. 16 mm - 63 mm

no stess with press

The MAINPRESS composite pipe system is an insoluble, long-lasting, dense and DVGW tested compound for the heating and sanitation field. The fixed press sleeve has small holes at the end as an observation window, which serves the visual control of the correct stop collar.
The MAINPRESS plastic pressing system sets the standard of processing and use in the field of heating and sanitation. It is ideally suited for a quick and safe assembly because it is easy to bend and yet retains its shape.

step 1

step 1

Mainpress composite pipe (diameter 16-25 mm) cross cut at right angles with shears or pipe cutters (from 32 mm diameter)! It is to be ensured that this results in a "straight cut".
step 2

step 2

Pipe is then deburred with an MP deburrer until the bevel is visible all round. The bevel is required so that the two connector O rings are not damaged when the pipe and the fitting are joined. It is essential that the bevel be checked before the fitting is inserted.
step 3

step 3

Plug the fitting into the Mainpress composite pipe up to the stop collar. The correct plug-in depth can be checked via the observation window.
step 4

step 4

Attach the pressing jaws to the sleeve between the stop collars. Then initiate the pressing process with the UAP 2 pressing machine (U contour jaws).
