Review on 💧 EKWB EK-Tube Zero Maintenance Soft Tubing, 9.5/15.9mm (3/8" ID, 5/8" OD), 3 Meter, Black: Durable and Hassle-Free Tubing for Optimal Liquid Cooling System by Joel Young

This control hose. Seriously.PRO: Constructed of material that will not degrade in water-cooled conditions. Doesn't stand up to heat, ozone, coolants, etc. - strong yet flexible. You can bend it quite a bit without over-bending it. You will never accidentally cut it - there are almost no marks on the sides of the hose. While this makes it harder to identify, it's also a lot prettier when finished. - Beautiful matte black finish. Reminds me of hoses from the automotive industry. - No plasticizers so you don't have to worry about the white-grey coarseness building up in your loop. CONS: - Use a hose cutter to do this. Don't try to cut it with a knife. Very difficult to slip off the fitting. Very difficult to compress with fittings. I suggest you use EK-ACF fittings to match this material.
