Product information

Description

Barrow THKN-3/8-V4 s is a compression fitting finished in silver, made for 16/10 (3/8") tubing used in liquid cooling and fluid systems. It provides a secure connection between rigid or soft tubes and system components where a 3/8" interface is required. The fitting is intended for assembling custom loops and linking radiators, pumps, reservoirs and other components while maintaining leak resistance and a compact profile.

Advantages

The compression design ensures a tight seal without the need for additional clamps, reducing the risk of leaks when installed correctly. The silver finish offers corrosion resistance and a neutral appearance that integrates with different system styles. Compatibility with 16/10 (3/8") tubing makes it suitable for common custom cooling configurations, and the compact form factor helps with space-constrained builds.

Suitable for

  • Custom liquid cooling loops in PCs
  • Connecting radiators, pumps and reservoirs with 16/10 (3/8") tubing
  • Replacing or upgrading existing compression fittings in fluid systems
  • Small or compact system builds where a low-profile fitting is needed

Key specifications

  • Tubing compatibility: 16/10 (3/8") outer/inner diameter
  • Connection type: compression fitting for 3/8" interface
  • Finish: silver
  • Material: metal alloy suitable for fluid system fittings
  • Application: liquid cooling and general low-pressure fluid systems

How to use

Ensure the tubing end is cut square and free of burrs, then slide the compression ring and nut onto the tube. Insert the tube fully into the fitting body until it seats against the internal stop. Hand-tighten the nut and then use a wrench to secure it further until the fitting compresses the tubing and forms a seal; avoid over-tightening to prevent tube deformation. After installation, pressurize the system and inspect for leaks, retightening slightly if necessary.

Usage recommendations

Use compatible 16/10 (3/8") tubing and follow manufacturer torque guidance when available. Test the assembled loop at low pressure first and monitor for leaks before regular operation. For long-term reliability, periodically inspect fittings and tubing for signs of wear, corrosion or loosening.
