Bykski

Bykski 3-Way Flow Indicator 5V ARGB G1/4 PMMA

SKU CH-7NW6-H4CKF

A square PMMA flow indicator with three G1/4 ports and 5 V addressable RGB lighting for custom water-cooling loops

  • TypeCPU Block
  • 3-way port layout enables flexible loop routing
  • PMMA construction provides clear coolant visibility
  • 5V addressable RGB adds synchronised lighting effects
  • Standard G1/4 threads fit common fittings directly
  • Square compact body suits tight build spaces

Three-way loop integration

The Bykski 3-Way Flow Indicator uses a square PMMA body with G1/4 threads on three faces to show coolant movement inside a custom water-cooling loop. Addressable 5 V RGB lighting lets the indicator match the rest of an illuminated build. It is aimed at enthusiasts assembling their own open-loop cooling systems.

Verify thread count and port caps

Confirm that your loop design has three G1/4 connection points available for this component. Port caps are not supplied, so you must source a plug for any unused port before pressure testing. The 5 V ARGB header requires a compatible motherboard or controller with a standard 3-pin 5 V pinout.

Acrylic clarity with standard fittings

The PMMA construction provides a clear view of the internal spinner while accepting any standard G1/4 compression or barb fittings. Three-sided port placement allows flexible routing but leaves one face permanently sealed, so plan the flow direction before final assembly. Handle the acrylic carefully during tightening to avoid stress fractures.

Questions about this item

What components are included and what must I purchase separately?

The box contains one Bykski 3-Way Flow Indicator with 5V ARGB lighting. G1/4 fittings and port caps are not included; you will need at least one cap to close the unused port and two fittings to connect tubing.

Which version should I choose for a standard G1/4 loop?

This single model uses a G1/4 thread on all three ports and a PMMA body with a black indicator wheel. It fits any standard G1/4 hard-tube or soft-tube fitting, so no other version is required.

What does the 5V ARGB header actually do once installed?

The 5V addressable RGB header powers the integrated LEDs inside the indicator wheel, allowing motherboard software to control colour, brightness and effects in sync with other 5V ARGB components.
