Need a Corny Pressure release valve....

[chris172]

As per title... not so easy though. Got a few to replace the ones that are looking a little sad on my tanks but one is different to the rest... a really stubby short one. Managed to break it when putting it back

Here are a couple more images. It's a short valve with a different rubber end on it too. Was going to cannibalise the 'standard' one... as seen in the pic... but the thread is different too

I have a useless Corny without this... any help to source please.

TIA
