At a Glance; Side-branch push-in tee for 4 mm pneumatic tubing
The AirCraft SG APDJ04 Insert T-Joint Side PU 4mm is made for neat, space-saving branching in small pneumatic systems. This side tee fitting lets you run a 4 mm tube line through while taking a clean side outlet for an extra tool, valve, gauge, or accessory. It’s a go-to connector for compact air layouts—airbrush stations, control panels, benches, and machinery—where fast push-in installation keeps everything tidy and easy to maintain.
Compact branching without the clutter
The side-branch tee design helps keep your tubing runs straight and organised while adding a take-off point exactly where you need it. Push-in collets grip the tube securely and release quickly for servicing or rerouting.
Extra Information
Suitable for pneumatic tubing such as PU and nylon (4 mm OD).
For best results, cut tubing square and clean, then insert fully until it bottoms out.
To release tubing, press the collet ring in and pull the tube out gently.
Pro Tip
Keep the branch line as short as practical and avoid tight bends—smooth airflow and tidy routing will reward you with fewer pressure drops and fewer leaks.
