Has anyone a detailed sectional drawing of the bottle connection and its clip-on adaptor, showing specifically the sealing arrangements?
I ask as a newly purchased un branded [made in Italy] adaptor leaks. I simply want to better understand how these are intended to seal.
Here its a 27mm but these, 20mm & 21mm seem to follow a common design where the sealing for coupling and the shutoff feature are embedded in the bottle's stem.
For those worried about my safety, I will simply bin this and probably buy another that looks as if it was made by some other manufacturer. It was only acquired to remove the need to move it across applications, a bit of de hassling.
Clearly the clip-on latches with a displaced collar that then seats into a groove on the stem. To get that into place the adaptor is pushed downwards and its "probe" has to enter the bottle, where I assume it seats into a seal?
Then, if the latch is "properly" seated it un locks and interlock enabling the latches lever to move into a position where it drives a pin in the probe into the bottle unseating a valve, allowing gas to flow. But how is all this done and where are the various seals needed, so I understand why this particular adaptor is weeping LPG?
PS its not primarily the bottle, as it is only this adaptor that leeks. The bottle's tolerances might be marginal and the adaptor work on another, that I have yet to explore , if I even bother.
