EK Water Blocks EKWB EK-Torque 90 Degree Angled Rotary Fitting, Black, 4-Pack

EKWB fittings have never let me down; the Allen key installation method is brilliant when using a plastic Allen key which encourages light use instead of gorilla strength for installation. The 90 degree fitting adapters from EKWB tend to change the dimensions you’ll need to keep in mind when running hard tubing. I been using EKWB 90 degree adaptors for years and have never once had an issue with leaking around the fittings. Both the black the nickel plated finish look amazing, they both are incredibly high quality and have amazing fitment. Water cooling fittings generally are very expensive, so it’s really nice that these adapters feel great in the hand; they have a pleasant weight to them and the surface finish is impeccable

These fittings look fantastic and make your build look professional. I think they were less than $10 more than other companies fittings but look twice as nice. This is where EK shines.

Water tight seal with great flexibility on running tubing.

Too bad it's expensive but they're quality
