AirCraft Red Insert Straight PU 12mm – 8mm (SG APGJ12-08)
At a Glance; Reducing straight push-in connector for 12 mm to 8 mm pneumatic tubing
The AirCraft SG APGJ12-08 Red Insert Straight PU 12mm – 8mm is a neat way to step down your air line from a high-flow 12 mm main run to an 8 mm tube without bulky adaptors. It’s ideal when you want the airflow capacity of a larger “backbone” line but need to connect to a slightly smaller circuit—such as a valve, cylinder feed, air accessory, or branch line. Push-in connections keep installation quick and tidy, while the colour-coded red body makes reducers easy to identify in busy pneumatic layouts.
Keep longer runs on 12 mm to reduce pressure drop, then reduce only where the 8 mm circuit begins. This keeps systems efficient, tidy, and easier to troubleshoot later.
