AirCraft Red Insert T-Joint PU 12mm – 10mm (SG APBJ12-10)
At a Glance; Reducing push-in tee: 12 mm main line to 10 mm branch connections
The AirCraft SG APBJ12-10 Red Insert T-Joint PU 12mm – 10mm is made for clean, high-flow pneumatic branching when your setup needs a strong main feed and slightly smaller distribution lines. It allows a 12 mm tube run through the tee while providing 10 mm branch connections—ideal for workshop air reticulation, machine circuits, manifolds, and installations where fast push-in fitment keeps downtime low and routing stays neat.
This reducing tee combines two jobs in one compact fitting: it splits your line and steps the tube size down at the same time. Fewer joiners means fewer potential leak points, while the push-in collet design makes tubing changes quick and simple.
