Compression joints and tapoured male /parrallel female joints

A man after my own heart - improvise, don't bodge!

Done that kind of think my self too many times to to count. Even tig welded stainless fittings together to get the required arrangement.

As you have done nothing but scoff and make out you're such a genius, surely you have all this available as holograms from your magic ' was chemist but now master of the universe ' arse...

Shame on you, Seajet. I take it you don't have the info requested. Congratulations, Vic for not responding.

It seems odd that I think I'm the culprit who first said "don't use PTFE with compression fittings" but Vic seems to have received the opprobrium!

On domestic plumbing I know that it is possible to use a standard compression fitting to adapt metric to imperial by using different olives provided the size difference is small. Maybe use a 3/8" fitting and 3/8"_& 8mm olives would work. BTW ignore 'invalidate insurance' advice just make sure that whatever you do is safe. As far as PTFE/sealant is concerned I only use the former on screwed fittings (shouldn't be used on the threaded part of compression fittings), I often use Boss white on olives but don't think it makes much difference. Some authorities recommend a gas equivalent on gas pipework but I would refer the calorgas website.

Hi Folks,

This must be a common issue where a new cooker is fitted in an older boat with different pipe sizes so I open to any ideas on how it can be achieved. I have not been able to source a reducing compression joint to fit both 3/8 and 8 mm .

I should have been clearer in my original thread and that may have avoided any misunderstanding

I have stopped using PTFE tape on any threaded fitting I have used loctite thread seal or the like and now get a 100% seal every time.

The big problem with olive compression fittings is that perople and sometimes myself over tighten then and they leak.

Some high pressure hydraulic "compression fittings" how have O-rings as the seal element so the fitting nut can be tightened at much as you like without damaging the O-ring and thus the seal of the fitting.

Hooked one!
