CUSTOM 3D PRINTABLE PVC FITTINGS – AUSTRALIAN PN18 SIZING

These fittings are designed to suit Australian PN18-labeled pressure pipe in 32mm, 25mm, and 20mm sizes, as sold at Bunnings.

IMPORTANT: THESE ARE NOT FOR PRESSURE SYSTEMS They follow PN18 sizing for compatibility, but do not meet any pressure certification standards. Use** only** in **non-pressure **applications like:

• Green screen rigs
• PVC framing
• DIY stands
• Garden structures

Pipe sizing in Australia (Yes, it's weird) Pipe sizes are based on internal diameter (ID), but fittings must match the outside diameter (OD) of the pipe.

• 32mm pipe = 34.0 mm OD
• 25mm pipe = 27.0 mm OD
• 20mm pipe = 22.0 mm OD

INSERTION DEPTH These parts are designed to fit those outer diameters with a 25 mm insertion depth for each connection. **Exception: **The AUS 20mm PVC PN180 Straight Coupler has no internal stoppers, allowing full pipe pass-through.
