C.MECH tubes are produced using a special co-polyester compound. C.MECH tubes fully comply with ISO 7628-2010 standards. C.MECH tubes are offering are an alternative to PA12 or PA11 tubes with some use restrictions regarding pressure and type of fittings. Based on customer requirements, other C.MECH tubes can be developed.

C.MECH tubes have been type-approved according to ISO 7628-2010 standard.
The ISO 7628-2010 standard classifies the tube resistance to pressure according to the temperature using some categories.
The following tables show the tube resistance:
The tolerances on external diameter, according to ISO 7628-2010, are:
External diameter from 6 mm to 10 mm ± 0,1 mm
External diameter from 12 mm to 15 mm ± 0,15 mm
Upon special request tubes with narrow tolerances.
