Clamp EK Water Blocks EK-HFB

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

Key specifications

• Material (barb): CNC-machined brass, nickel-plated
• Material (ring): CNC-machined aluminium
• Sealing: O-rings included
• Compatibility: EK-AF series 45°/90° angled adapters
• Installation: Requires hose clamp or similar; hand-tightenable or 9 mm Allen key
• Dimensions (from product data): height 19 mm, diameter 19.8 mm, thread diameter 12 mm
• Materials listed in product data: EPDM, PVC, silicone (related clamp materials)

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.

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.
