greenDracaena G1/4" 15mm Male-Female Extender Fittings 12 Pack Black

Loop Clearance Solved

These 12 black G1/4" male-to-female extender fittings add 15 mm of spacing to any standard PC liquid-cooling loop. Chrome-plated brass construction provides corrosion resistance and good thermal conductivity. A concealed O-ring groove seals without tools, making installation quick and reliable for custom water-cooling builders.

Replaces Rigid Spacers

When fixed-length tubing or direct-thread components leave no room for bends or component clearance, these extenders create the needed gap without extra adapters. The jump is worth it whenever a pump, reservoir, radiator or block sits fractions too close for a clean tube run, letting you keep the original fittings and avoid a full loop redesign.

Handles Standard Loop Pressure

Each fitting’s 18 mm outer diameter and brass threads comfortably withstand typical closed-loop pressures and coolant temperatures. The 12-pack covers dual-radiator builds with multiple right-angle or rotary joints. They do not add flow restriction beyond the thread length, but they cannot compensate for mismatched thread standards or replace a missing port on a component.
