Tridata depth sonar

[bluetooth]

My depth sonar leaks the oily fluid. Appears the plastic 'ring' has one broken locking pieces (of the 2). Didn't realise it came away as thought it was one piece. Having ordered a replacement it then became obvious. The unit otherwise works well so haven't used it yet.

Question - does anyone know if you can order the plastic ring separately ?

So I figured this with further chats and pics to suppliers ...
This is the part I need - Airmar 20-264-01
Parts inc as per pic

Been told I can use cooking oil as medium - unused and clean obviously !! - and works

Thanks. I guess the main requirement of the fluid is that it doesn't freeze.
