Barrow kompressioliitin THKN-3/8-B03 b, 13/10 mm (sisä/ulko), musta

Barrow compression fitting THKN-3/8-B03 b is a black compression connector designed for 13/10 mm (outer/inner) soft tubing used in PC liquid-cooling loops and custom cooling assemblies. The fitting creates a push-on compression seal between tubing and cooling components, providing a compact, low-profile connection for runs where 13 mm outer diameter and 10 mm inner bore tubing is specified.

Advantages

The fitting offers reliable mechanical compression sealing without the need for additional clamps or adhesives, reducing the risk of leaks when installed correctly. Its black finish provides visual consistency in systems with dark tubing or components and helps hide wear marks. The push-on design simplifies installation and removal while maintaining a secure hold under standard operating pressures for typical PC liquid-cooling setups.

Suitable for

• PC water-cooling loops using 13 mm outer / 10 mm inner soft tubing
• Custom liquid-cooling assemblies and tubing runs in desktop systems
• Connections between tubing and radiators, pumps, reservoirs, and water blocks with matching ports
• DIY repairs and upgrades where a compact compression fitting is required

Key specifications

• Finish: black
• Tube compatibility: 13 mm outer diameter, 10 mm inner diameter
• Connection type: push-on compression
• Application: liquid-cooling tubing connector for PC systems
• Form factor: compact, low-profile fitting suitable for tight routing

How to use

Ensure the tubing end is cut square and free of debris before installation. Slide the tubing over the fitting until the compression seat is reached and a snug feel confirms engagement. For best results, push firmly until the tubing abuts the end stop; avoid twisting the tubing excessively during insertion. Verify the connection by visually confirming the tubing has fully seated and by testing the loop under low pressure before powering the system.

Recommendations

Use only with soft tubing of the stated dimensions. Inspect fittings and tubing periodically for signs of wear or softening, and perform a pressure or leak test after any maintenance or reconfiguration. Do not exceed the typical operating temperatures and pressures recommended for PC liquid-cooling components.
