A replacement seal for the Paterson System 4 Tank.

It's a good push fit and best printed in flexible material.

Printed in TPU.

Variable layer height -

0mm to 3mm – 0.3mm
3mm to 12mm – 0.15mm

100% infill

Had better results with 2 perimeters over 4, probably due to fairly thin wall starting at 3mm layer.
