I faintly recall reading (Hakko) the (small) gap is intentional and suction makes the rubber flex and seal in place. Otherwise it gets burned due to the heat. The metal tube is at soldering temps.
I'd make a 3D printed part and then mould it out of silicone to conquer this crap.
My Hakko 470/809 just cratered, the tip had something inside like a blob of lead-free solder or a lead cutting that I could not get out. It's soldered in basically and I'd have to take a torch to the tip to heat it up and scrape the insides.
So I'm just getting a new Ali tip and see if that fixes it from constantly clogging. But I had to take it apart so many times it wrecks the filter.
The 1mm poker is essential but useless sometimes.
It was the lead-free solder that killer her. Hasn't worked well since.
