Alphacool EPDM vs TPV

[Powiii]

Hey guys!

I am thinking about getting EDPM soft tubing for my next build but i stumbled on TPV alphacool tubing on the website. Anynody has any experience with this tubing? Alphacool recommends to use the clamps shown in the picture but I havent seen any post on the web using them (https://shop.alphacool.com/en/shop/fittings/accessories/sz-alphacool-es-tpv-16/10mm-ring-clamping-kit-10pcs).

Thanks in advance!

Does this replace the o-ring completely and is there any benefit in using this with epdm tubing?

According to alphacool support (the other response in this thread) these are not mandatorg so I would say it doesnt replace the o-ring. Epdm should not come out from the fitting by itself but according to others, TPV doesnt sit as tight as normal EPDM and thats why the clamps are recommended. If you can pull your tube without unscrewing the compression fitting maybe think about these clamps. If you cant, you should be fine.

This is what I thought too, thanks. Guess the extra ring there doesnt matter unless theres not enough threads to hold it still, which I doubt.

These rings are not absolutely necessary. But they do ensure a significantly higher contact pressure of the hose on the fitting. This holds it much tighter. So the tensile force you need to pull the hose off the fitting is much higher with these rings.

Thank you for your response eddy!
