It is possible to push a host clamp over the attached tubing end to clamp it tightly to the connector. For a good sealing we recommend our mp-hc which gives a good sealing regarding leaking. Another option is to use a wire ferrule. The ferrule doesn’t have to be crimped. If crimping is required for a very strong fixation, please make sure that the ferrule does not create such a deformation that a gap appears again. With mp6 and Tygon tubing (mp-t ID 1.3) a wire ferrule for 4 mm² (internal diameter 2.8 mm) is very good. For other tubing ferrules with other diameter have to be tested.
