Stessco Bung Surround

We keep getting asked about this one — the bung surround is one of those Stessco parts that fails long before the rest of the unit is done. With your sample on the bench this is a realistic reproduction job.

Why these break

Bung housings crack and weep. Heat cycling is the killer here: years of expanding and contracting work-hardens the plastic until a routine bump becomes the final straw.

How we reproduce them

The process is simple: drop the part in or send clear photos with a ruler in frame, we confirm fit details, and print replacements — often with a little extra material where the original always cracked.

We print these in ASA. ASA is the UV-stable cousin of ABS — it holds its colour and strength through years of Australian sun where the original plastic went chalky and brittle.

As with everything in our library: whether a part can be reproduced depends on size, load, heat, material, and having a decent sample to work from. Send photos first — the assessment costs you nothing, and we'll tell you honestly if a genuine spare is the better option.
