Hard acrylic usually has an interference fit so easy pull through, cut and stay put. You may need to try different tubes until you get the best fit. With soft silicon I have to use a dab of glue to stop my anticondensation tubes from slipping.
I think there are three thicknesses of tubes but not sure.
It depends on the person. I used hard shell earmolds for a long time, needs to be changed about every year or two. I have tried soft silicone that sticks to the ear better but the soft material inflamed the concha area of my ears so l stop using soft earmolds.
I don’t think my university audiologist knows how to do this, or she would have done it. Any advice about how to find an audiologist in the area that can do it? I’m in the northeast corner of the Raleigh-Durham-Chapel Hill Triangle in North Carolina.
You can also request earmolds with an elbow (if I named it correctly). Then, you should only need to change the tube every few months.
@corrado - Good idea. Best to have an audiologist show you how to take apart the ear mold but here is an illustration of two different ways you can do this. I can’t believe your normal audiologist doesn’t know what to do here. But yes, you can easily break your hearing aid if you pull too hard with earmold tubing that has hardened.

Besides the good advice about removing/replacing the tubes, including that they become hard, I advise you clean the two openings in each mold with a soft “wire” but NOT a stiff steel wire.
A nylon “wire” of the right size will help remove earwax. My audiologist gave me a couple cleaning strings but I still need a wire to push them through the holes in the mold.
FYI, I have a Phonak Naida Link M for one ear with an Advanced Bionics cochlear implant for the other ear. They work together although I find the AB app more primitive than advanced. The Easyline app for KS10 HA’s is better.
