EK ZMT (Zero Maintainance Tubing) is a high quality, zero maintenance industrial grade EPDM rubber tubing in stylish matte black.
This tubing is – just like Norprene – designed to withstand harsh conditions for a very long period of time, offering a truly exceptional lifespan even under UV, ozone and heat exposure for many years.
Unlike most PVC and PUR tubing this high-quality EK made EPDM rubber tubing ensures long-lasting operation and does not suffer from plasticizer leaching effect which can cause a blockage (gunking) in your liquid cooling loop. This 9,5/15,9mm (ID/OD) tubing also allows for a very small bend radius!
This may not be the tubing for everyone but it is guaranteed to be hassle-free even in the long run which is something other PVC/PUR tubing cannot offer!

This tubing is very easy to work with. It is almost impossible to kink, and won’t unless you are deliberately trying to. I also think the plain black tubing looks really slick, but that is subjective. No plasticizer so should last a lot longer than regular tubing as well
Used ZMT tube recently for a test bench and really liked it. I will be considering it for my next build as I get tired of hard tubing looks in the past two builds.
