01AUTOMOTIVE REPAIR & SPECIALITY TOOLS
Precision control for your aquarium air system
The quiet hum of an air pump is the heartbeat of any aquatic display, yet controlling that breath requires more than just a switch. These ten small black valves offer a tactile way to manage the invisible currents within your tank.
Designed for 4mm tubing, each connector allows you to split the line to power a second stone or merge inputs for stronger output. They suit hobbyists who value precise, hands-on adjustment of their system's rhythm.


02MATERIALS
Robust plastic built for long service life
Crafted from high-quality plastic, these connectors are designed to withstand the constant pressure of compressed air without warping or cracking. The material is strong and durable, ensuring a long service life even in humid environments typical of aquaculture setups. Their matte black finish blends discreetly into most tank stands and equipment racks.

04INSTALLATION
Direct insertion into existing pipelines
Installation requires no tools or adhesives; simply insert the connector directly into the air pipe. The design accommodates standard 4mm diameter tubing, ensuring a snug fit that holds firmly in place. With ten pieces included, you have enough to configure complex branching systems or replace worn components across multiple tanks.
ADJUSTMENT
Fine-tune gas volume with a quarter turn
Controlling the flow is as simple as turning the valve 90 degrees from full shut to full open. This manual regulation allows for precise adjustments to the gas volume, letting you dial in the exact bubble rate needed for different areas of the aquarium or specific biological requirements.
