How about Naida? Can I fit a SlimTube SDS 4.0 on a Naida B or earlier device?

A: Yes, that is possible since Naida always had the spout with an external thread. However, it is not recommended since the precalculation does not take the new tube diameter into account and the mechanical fit at the transition of the tube interface to the housing is not given.

Can I fit a SDS 4.0 SlimTube onto a Bolero B device or vice versa?

A: No. All Belong and earlier devices had an internal thread. Therefore only SDS 3.0 SlimTubes fit. Bolero M has an external thread.

Can I fit a SDS 3.0 SlimTube onto a Bolero M device or vice versa?
