M40 / M140
Data Sheet
The M40 (length 40 mm) is used for joining thin walled pipes to concrete main sewers or concrete manholes.
The M140 (length 140 mm) corresponds to its construction of M40, however it can be cut to the wall thickness of the main sewer or chamber.
Both seals are manufactured from high quality EPDM rubber according to
DIN EN 681-1.
Beside the standard seals of M40 / M140 (listed in the Data Sheet), they can be produced for any pipe material up to dimension DN 300, calculating the equivalent cutting length for the corresponding pipe outside diameter.
