MULTILAYER
C.MLT 533
C.MLT 533 tubes are produced using state-of-the-art multilayer extrusion technology. They fully comply with ISO 7628-2010 standards. C.MLT 533 tubes are offering are a very cost-effective alternative to PA12 or PA11 tubes. Developed for Airbrake application using quick connectors, C.MLT 533 tubes are available in black color only. Based on customer specifications, other C.MLT structures can be developed.

C.MLT 533 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.
