EK-Tube ZMT Matte Black 15,9/9,5mm (3m Retail)

Grabbed this to set up an external radiator setup for my watercooled rig with some quick disconnects. These tubes are very thick and unfortunately EK does not produce torque fittings for this size tubing but plenty of other fitting manufacturers do so it ends up being very easy to work with. Them being this thick does make it harder to make it bend or flex but not impossible and you can route them wherever you want as long as you give it a little more length to make the curve instead of bending. Flow will not be impeded as the tube is about as wide as the internals of most G1/4 fittings.Great if things need to have high flow but harder to work with than other tubing sizes and quite a bit harder to make the bends needed to do tube routing within the case.Recommended for short runs that need high flow.

I have been building water cooling loops for computers before it was a commercialized option. Currently, my own system doesn't even use radiator(s) and instead uses active water chillers. From the moment I first tried this tubing I could tell just by the feel of it that it was radically different from other soft tubing I had used in the past. I was amazed at how flexible it was - very resistant to kinking - and yet it is very strong. Not sure why this specific tubing is so different from other tubing that seems to be made out of the same material but I suspect it must be from the manufacturing process. Whatever the difference is I really love this tubing - enough to actually take the time to review it.

It was exactly what I was wanting.

Best tuning on the market. Simple to work with and durable. Black goes with everything, basically.

I've used ZMT on a few builds and it's always easy to use and looks great. Cuts clean, and kinks less readily. Best of all it stays looking great for years, unlike any of the hardline stuff or other soft tube I've used.

It works. I like some good hoes.

This tube has wall thickness of 1/4". It could handle tight turn without kinks. To hand tight the compression fittings with this soft tube need some strength. I was able to install it without tool nor do I use heat gun. I suggest you pre install the one that has tight space first. In one connection, I have a situation where the tube is installed pretty tight on to compression fitting, but the tube has the tendency to twist the g1/4 thread loose once I let go. In this case, one of the option is to use hex wrench to tighten the g1/4 thread so that it bites into thread thread a bit more to resist the force of the twisted energy from the soft tube.

This hose rules. Seriously.PRO:-made of a material that will not degrade from watercooling conditions. Doesn't mind the heat, the ozone, the coolant, etc.-firm-yet-flexible. You can bend it pretty tightly, without kinking it. You'd never manage to cut it on accident.-almost zero labeling down the side of the hose. While this makes identifying it harder, it's also a lot prettier in a finished build.-Nice matte-black finish. Reminds me of the hoses used in the automotive industry.-No plasticizers, so you don't need to worry about accumulating that white-grey grossness inside your loop.CON:-Use a hose cutter for this stuff. Don't try to cut it with a knife.-Very stiff to slip over a fitting. Very stiff to compress using fittings. I suggest you use the EK-ACF fittings to match this stuff.
