Replacement Interval for Material Station Bowden Tubes

[dcschooley 9]

Is there are recommended replacement interval for the Bowden tubes that connect the Material Station to the S5? The recommended interval for the printer itself is one year, and Ultimaker sells replacements, presumably of the correct length. Ultimaker doesn't sell replacements for the Material Station to Printer tubes. 

 

I had some PLA that broke in multiple places. One of the pieces got stuck between the Material Station and the printer. I managed to get the filament out of the tube thanks to advice on the forum, but in the meantime I ordered a replacement tube, but that one will be too long for the Material Station. I'll use it for the S5 now that the Material Station is fixed, but that's what got me to thinking about a maintenance interval for the Material Station tubes.

There is a Bowden tube set for the Material Station. It has the UM part no. 219542 and should be available from a prefered Ultimaker reseller. Some resellers might also offer you Bowden tubes with custom length.
