## Description

EK-Torque STC 10/16 Black fittings are EK's new minimalistic 10/16mm (ID/OD) soft-tube compression fittings designed for use with various flexible soft tubing types such as PVC, EPDM, Norprene, silicone or any other type of compatible flexible tube. With a non-intrusive, yet striking look, and with NO added branding at all. They can be complemented by interchangeable aesthetic color rings, and are an ideal choice for anyone and a perfect match with EK-Quantum series products.The locking ring prevents solid tube to be pulled out of the fitting by compressing the rubber gasket underneath the ring. The grooves on the outside allow for easier hand tightening. The compression ring has cutouts in EKWB Quantum signature shape allowing for the colored aesthetic ring to be shown. The colored rings are available in many colors and are screwed onto the fitting before the compression locking ring. The aesthetic rings are sold separately.The fitting barb and the compression rings are covered with a unique, high-quality black finish. Both are made of CNC machined brass and the seal is made quality rubber O-rings.The base fitting surface is smooth and has no adequate gripping surface, but the inside of the barb is socketed with a 9mm hex Allen key pattern. It's highly recommended to use an Allen Key 9mm (purchased separately) to prevent skin damage to the fingertips while installing the fitting.

Review: Best of the best - I already had 6 of these in my system but finding the nickel ones at my local microcenter can be a pain. I like the thicker look of 16mm tubes but EKWB Quantum fittings always work really well and they're easy to unscrew when it comes time to swap out tubing. I've never had any of these fittings leak. Currently running 10 of these in system and I plan to stick with these going forward.
Review: Only complaint, expensive. - I went a little nuts and impulse ordered a complete water cooling kit and ordered these, I found them cheaper at Titan Rig. Seemling a lot less, I'm fine with a little more but twice seems expensive. The work great, look great, everything is great about, I don't know how you could make them better.

### ⭐⭐⭐⭐⭐ Very easy to use, no leaks
*by T***S on May 28, 2021*

I bought two different styles, and this is the one I came back to get more. I am using soft tubing, and these hold everything tight and without any leaking. The gripping area is longer than the other style I tried, and the rubber seal on the bottom is compressed properly and not damaged with removing and reuse. I highly recommend these
