AirCraft Red Insert Straight PU 8mm – 6mm (SG APGJ08-06)
At a Glance; Reducing straight push-in connector for 8 mm to 6 mm pneumatic tubing
The AirCraft SG APGJ08-06 Red Insert Straight PU 8mm – 6mm is a tidy way to transition from an 8 mm main air line to a 6 mm tube without bulky adaptors. It’s ideal when you want the flow capacity of an 8 mm “backbone” run but need to connect to a smaller circuit—such as a valve, cylinder feed, pilot line, gauge, or compact air accessory. Push-in connections make installation quick, while the colour-coded red body helps you identify reducers instantly in a busy pneumatic system.
Standout feature: clean step-down from 8 mm to 6 mm
Keep the larger line for longer runs to reduce pressure drop, then reduce only where the smaller circuit begins. This makes air systems neater, more efficient, and easier to maintain.
Extra Information
Designed for pneumatic tubing such as PU and nylon in 8 mm and 6 mm OD.
For best sealing, cut tubing square and clean and push fully into each end until it seats.
To remove tubing, press the collet ring in and withdraw the tube gently.
Pro Tip
Fit the reducer close to the smaller component so most of the run stays 8 mm—this helps keep pressure drop low and improves tool performance.
Features
Reducing straight connector Joins 8 mm tubing to 6 mm tubing in a straight run.
Push-in tube connections Quick-connect collets for fast installation and servicing.
Colour-coded (Red) Easy identification of reducing fittings in your air line network.
Compact design Ideal for tight panels, machines and workshop air layouts.
Benefits
Neat transitions: Reduce tube size cleanly without extra adaptors and clutter.
Faster maintenance: Push-in fittings make line changes quick and tidy.
Better airflow planning: Keep higher flow on 8 mm runs and reduce only where needed.
Safety
Wear eye protection when working with pressurised air lines.
Depressurise the system before installing, removing, or adjusting pneumatic fittings.
Route tubing to avoid kinks, abrasion and snag points that can cause leaks or failure.
Do not exceed the rated limits of your compressor, regulator, hoses and fittings.
