    Im switching to hardtubing and I have a few question, and any advice somebody may be able to give.

    1. Do I need to chamfer this crystal link non chamfer? whats the best way?

    2. Are the tools and parts linked correct?

    3. I have a 2000W Black n Decker heat gun with an adjustable knob, what range should I be using for this PETG?

    4. Is it preferred or essentional to change things, while keeping in mind I need to buy new ones?

    The parts and tool I have that I cant exchange.

    Hello Walid and welcome to the forums.

    1. I've never used Bitspower's 'non-chamfer' tubing, actually I have never used PETG based tubes. But I'm pretty sure the both ends of a piece are already chamfered and need no further treatment. If you do a cut however, the edges of this cut need to be smoothed in order to 1) not damage the o-rings and 2) properly fit in. You can use the the drill bit you've purchased or the manual deburring tool included in the XSPC-bend-kit for that.
    2. Although Bitspower suggests to only use fittings from their EML-series (on their pages), I don't see a problem to use the ones you have, as they are designed for an outer diameter of 16mm as well.
    3. You can vary the heat applied to the tube by moving it further away from or closer to the heat source. I think it can be bend already below <100°C, but I'm not sure. You will however notice when the time has come while heating it up, it will get unstable / start to sag. Don't heat it to fast. Move/rotate it while heating. Don't just heat up the exact spot you are planning to bend, but also a small area left and right of it. This will prevent the material from being stressed too much by the bending and reduce tensions inside the PETG. At least that is the case for acrylic tubing. I suppose you'll have to experiment a little with this in order to get a feeling for it. There probably tutorials available on YouTube, showing the actual process.
    4. If you are satisfied with the materials you chose, there is nothing to criticized imho.
    If you have any further questions, just ask.
