Know before you buy
These fittings are designed specifically for 12/16mm (ID/OD) soft tubing. They are compatible with common materials including PVC, EPDM, Norprene, and silicone.
You can tighten the outer locking ring by hand using the integrated grip grooves. For the internal barb, you will need an 8mm Allen key to secure it properly to your cooling components.
Yes, these fittings feature interchangeable aesthetic rings that sit behind the locking mechanism. You can purchase these color rings separately to customize the look of your loop.
These fittings use a standard G1/4 BSPP thread, which is the industry standard for liquid cooling. While they are guaranteed to work with all EK Water Blocks products, they will fit any component that utilizes a standard G1/4 port.
The locking ring compresses the tubing against the barb, creating a secure seal that prevents the tube from pulling off under pressure. This provides extra peace of mind compared to standard barbed fittings that rely solely on friction or hose clamps.
