Monotubes are particularly adapted for installations subjected to external aggressions, such as sparks, for example. they can be connected by push-in fittings after stripping the sheath at the ends.
Marking of monotubes is as follows : “tecalemit flexibles - part N° - monotube - ID - batch N°”

The polyamide coextruded TAT is a polyamide monotube covered by a hypalon sheath comprised of a MANURIL® tube as described in paragraph 3-1 which is then covered by a layer of chlorosulfonated polyethylene synthetic rubber (hypalon, trade name of Dupont de nemours).
Coextruded TAT is :
- very resistant to oil and air.
- very resistant to abrasion and tearing.
- very resistant to ozone and atmospheric agents.
Coextruded TAT is used for the transfer of fuels in high ambient temperature engine compartments.
They can be preformed.
Admissible temperature range is from -40°C to +80°C in an atmosphere of 140°C (with peaks to 150°C)
Marking of coextruded TAT is as follows : “tecalemit fexibles - part N° - IDxMDxOD - pa12 hypalon - batch N° (white ink)”

The values of working pressure ratios according to working temperatures indicated above represent only the average of the results obtained from burst pressures divided by a safety factor, given that these are variable according to tube diameter and wall thickness.
