Four black sparkle compression fittings with knurled collars and G1/4 threads

Bitspower

Bitspower G1/4" Black Sparkle Compression Fitting CC3 V3 for Tygon 3603 (4 pcs)

SKU CH-N96H-H05WQ

Four compression fittings with G1/4" threads designed for Tygon 3603 tubing

  • True Hi-Flow design maximises coolant throughput
  • High-quality brass body ensures long-term reliability
  • Nickel-plated Black Sparkle finish resists corrosion and wear
  • Concealed O-ring layout creates a clean seal line
  • World-first compression fitting tailored for Tygon 3603 tubing

Designed for Tygon 3603 tubing

These G1/4" compression fittings are engineered specifically for Tygon 3603 tubing with a 3/8" inner diameter and 5/8" outer diameter. The four-piece set suits custom liquid-cooling loops that require a secure, high-flow connection. Builders using other tubing dimensions cannot use these fittings.

Sustained sealing under pressure

The hidden O-ring design keeps the seal protected from coolant flow and mechanical stress during continuous operation. Brass construction with a durable nickel finish resists corrosion over long periods. The true hi-flow internal geometry maintains consistent coolant velocity without creating turbulence that could degrade performance over time.

G1/4" thread compatibility limits

Each fitting provides a 5 mm thread length for standard G1/4" ports found on water blocks, radiators and reservoirs. The fixed tubing specification means the fitting cannot adapt to smaller or larger outer diameters. Installers must verify that their components accept the exact 5/8" OD size before assembly.

Questions about this item

Does the fitting generate any noise or heat when the loop runs continuously?

No, the brass compression fitting is a passive component with no moving parts, so it produces no noise or heat during continuous operation.

What tubing must I already have for these fittings to work?

You need Tygon 3603 tubing with an inner diameter of 3/8 inch, outer diameter of 5/8 inch and a wall thickness of 1/8 inch.

Will these G1/4″ fittings thread into the older G1/4″ ports on my existing radiators and blocks?

Yes, the G1/4″ thread matches the standard port size used on most water-cooling components, so they screw directly into your current hardware.
