## Long description

EK-HFB Fitting is a high-flow barb-style fitting designed for liquid cooling systems. The barb section is CNC-machined brass with nickel plating and quality O-rings, while the outer ring is CNC-machined aluminium. It is compatible with EK-AF series 45° and 90° angled adapters and requires hose clamps or similar fasteners for secure installation.
Advantages
The fitting combines a nickel-plated brass barb for corrosion resistance and reliable sealing with a lightweight CNC aluminium ring for structural support. Its compatibility with EK-AF 45°/90° adapters allows flexible routing in cooling loops. The design permits hand tightening or use of a 9 mm Allen key (not included) for a firmer fit.
Suitable for
PC liquid cooling loops using soft tubing
Setups requiring EK-AF 45°/90° angled adapters
Applications where high-flow barb connections are preferred

How to use
Slide the soft tubing onto the barb until it seats against the O-ring. Place an appropriate hose clamp over the tubing and position it above the barb’s ridges, then tighten the clamp to secure the tubing. If additional torque is required on the outer ring, tighten by hand or use a 9 mm Allen key (not included). Verify compatibility and secure fit with any EK-AF 45°/90° adapters before running the system.
Usage recommendations
Use quality EPDM, PVC or silicone tubing sized to match the barb and clamp. Always use a hose clamp or equivalent fastener for leak-free operation. Do not overtighten the fitting or clamp to avoid damaging tubing or O-rings. Keep a 9 mm Allen key available if you prefer a firmer mechanical connection.
