SKU CH-1B23-7NDE6 MPN THKN-3/8-V4

Four white compression fittings connect 10 mm inner by 16 mm outer soft tubing to standard G1/4 water-cooling ports

  • Durable construction backed by double electroplated H59 brass
  • Secure tubing hold via ultra-tight compression anti-off design
  • Easy installation grip from non-slip diamond knurling
  • Universal G1/4 thread fits standard water-cooling components
  • Clean white finish resists peeling through chromatizing process

Fittings for 10/16 mm soft tubing

These compression fittings connect 3/8 inch inner diameter and 5/8 inch outer diameter tubing to a standard G1/4 inch water cooling loop. The 4-pack supplies enough connectors for a typical CPU and GPU block setup. They suit builders assembling a custom liquid cooling system with white accent tubing.

H59 brass construction handles loop pressure

The high-quality H59 brass body resists corrosion and maintains structural integrity under continuous coolant flow. The ultra-tight compression design creates a reliable seal that prevents the tubing from sliding off during operation. Double surface electroplating protects the white finish from peeling or fading over time.

Non-slip diamond pattern eases installation

Knurled collars with diamond-textured grips allow firm hand-tightening without tools, reducing the risk of over-torquing the brass threads. Standard G1/4 inch threads ensure compatibility with most water blocks, radiators, reservoirs and pumps on the market. White colourway coordinates with matching Barrow Mods components for a uniform aesthetic.

Questions about this item

Will these G1/4" compression fittings thread into the water blocks and radiators I already own?

Yes, the G1/4" thread is the standard interface used by most water cooling components, so they will connect to existing blocks, radiators and reservoirs that share that thread.

How can I confirm the fittings are sealed properly after installation?

Press the 10 mm inner-diameter tubing fully into each fitting until it seats against the internal stop, then tighten the compression collar by hand plus a quarter turn with a wrench; run the loop at low pump speed and inspect every joint for drips.

The pack contains four white fittings — do I need to buy tubing, coolant or tools separately?

The pack includes only the four compression fittings; you must supply 10/16 mm soft tubing, coolant and a suitable wrench for final tightening.
