Product information

Description

Barrow compression fitting THKN-3/8-B03 s is a silver-coloured connector designed for 13/10 mm tubing. It creates a compression-style seal that secures tubing to components in liquid cooling loops and fluid transfer systems. The fitting is intended for applications that require a compact, metal compression connection for 13/10 mm soft or reinforced tubing, providing a neat external finish and a reliable mechanical hold.

Advantages

The fitting offers a metal compression design that improves durability and resistance to deformation compared with plastic alternatives. Its silver finish provides a neutral aesthetic that integrates well with a variety of system builds. The compression mechanism forms a tight seal without the need for glue or clamps, simplifying installation and maintenance while enabling leak-resistant connections when properly fitted.

Suitable for

  • Custom PC water cooling loops using 13/10 mm tubing
  • Small fluid transfer lines in electronics cooling or lab setups
  • Upgrading or replacing existing compression fittings in compact systems

Key specifications

  • Material: metal body with compression ring (silver finish)
  • Tube compatibility: 13 mm outer diameter / 10 mm inner diameter tubing
  • Connection type: compression-style seal for tube-to-component joints
  • Intended application: low-pressure liquid cooling and fluid transfer
  • Finish: silver (metallic)

How to use

Slide the compression nut and compression ring onto the tubing, insert the tube end fully into the fitting until it seats against the internal stop, then tighten the nut by hand and finish with a suitable spanner to achieve a firm compression seal. Do not overtighten; stop when the nut is snug and the tube is held securely. After installation, pressurize the system and inspect the joint for leaks, then retighten slightly if necessary.

Usage recommendations

Use compatible 13/10 mm tubing and ensure tube ends are cut square for best sealing performance. Periodically check fittings in systems subjected to thermal cycling or vibration. For initial leak testing, use low-pressure fluid or a controlled pressure source and inspect visually for any signs of seepage.
