Notes
- PU pneumatic tube, OD × ID: 4×2.5, 6×4, 8×5.5, 10×6.5, 12×8 mm; each file is a 50 mm length at exact OD and ID.
- It is stiff tube made for push-fit fittings, typically rated 10 bar.
- Push-fit fittings grip the tube OD, so the push-fit socket is drawn at the tube OD exactly.
- On my pressurised engines the line is 6 mm PU into push-fits.
