AirCraft Red Insert Straight PU 6mm – 4mm (SG APGJ06-04)
At a Glance; Reducing straight push-in connector for 6 mm to 4 mm pneumatic tubing
The AirCraft SG APGJ06-04 Red Insert Straight PU 6mm – 4mm is the simple, tidy way to step down your air line from a 6 mm main run to a 4 mm tube. Whether you’re feeding a compact valve, pilot line, gauge, airbrush line, or a smaller pneumatic accessory, this reducing straight connector keeps your setup clean without stacking adaptors. Push-in connections make installation quick, while the colour-coded red body helps you spot reducers instantly in a busy air system.
Standout feature: clean step-down from 6 mm to 4 mm
Maintain better airflow on the larger line, then reduce only where you need tighter routing or smaller components. This approach keeps your system efficient and easier to troubleshoot later.
