Clamp EK Water Blocks EK-HFB

EK-HFB Fitting is a high-flow barb fitting designed for PC liquid cooling systems. The fitting combines a nickel-plated CNC-machined brass barb with a CNC-machined aluminium ring and quality O-rings. It is compatible with EK-AF series 45° and 90° angled adapters and requires hose clamps or a similar fastening method for safe installation.

Advantages

The nickel-plated brass barb offers corrosion resistance and precise machining for a reliable seal, while the aluminium ring provides a lightweight, durable clamping surface. O-rings ensure leak prevention under typical operating conditions. Compatibility with EK-AF angled adapters increases installation flexibility in complex liquid cooling loops.

Suitable for

• Custom PC liquid cooling loops
• Connecting tubing to radiators, pumps, and water blocks
• Systems requiring EK-AF 45° or 90° angled adapters

Key specifications

• Brand: EK Water Blocks
• Model: EK-HFB
• Materials: nickel-plated brass barb, CNC-machined aluminium ring, O-rings (EPDM/silicone as applicable)
• Compatibility: EK-AF series 45°/90° angled adapters
• Installation: requires hose clamps or similar; can be hand-tightened or tightened with a 9 mm Allen key (not included)

How to use

Slide the tubing onto the barb until it seats against the O-ring. Fit an appropriate hose clamp over the tubing and position it over the barb section, then tighten evenly to secure the connection. The fitting can be finger-tightened and then snugged with a 9 mm Allen key if additional clamping force is required (Allen key sold separately). Ensure compatibility with the chosen tubing material and clamp type before final installation.

Recommendations

Use quality hose clamps compatible with the tubing material (EPDM, PVC, silicone) and avoid over-tightening to prevent tubing damage. Verify O-ring condition during maintenance and replace if degraded. Confirm EK-AF adapter compatibility when planning angled connections.
