Air con pipes and bits and pieces

[BongoBongo123]

After a re-gas the Bongo air con works well but then by 3-4 weeks is 50-70pct less well at cooling so a leak suspected.

Going to a local place to get leak testing done, nitrogen and UV/Dye. (I appreciate a basic re-gas tests for obvious big leaks, I had it done a month ago
and already the air con performance has dropped off)

Just trying to pre-empt some old hoses being brittle / having a slow leak... what are the air con parts availability such as rubber hoses etc. ?
Or are they easily made from standard bore rubber hose ?

It might just need some pipes reseating with luck but you know.... 30 year old rubber !

I guess aircon gas is in a combination of aluminium and rubber pipping ?

Just trying to know a little more than I do about the pipes

Did a bit of a search and found these digrams from other posts:

Useful to to print out.

Are Japanese rubber pipe bores standard-ish /similar to UK ones ? (Can one cut standard rubber pipe and reclip if need be) I am guessing the original parts are non existent now.

Jumping the gun on faults of course but just curious.

Cheers

The pipe diameters have changed over the years from around 2000 and after they changed to a smaller diameter pipe.
"There are three possibilities depending on age and what is still working!
All use R134a refrigerant and PAG46 oil.

A full system prior to around 2000;
950 Grams & 14ml of oil.

If the rear air con system has been sealed then 700 Grams of refrigerant & 14ml of oil.

After 2000 (smaller diameter pipes were introduced) then 750grammes & 50ml of oil."
