AP make an 18mm valve

You are quite right. I had honestly forgotten about that.
When we were asked to carry out a particular accident investigation on, we pondered long and hard, but in the end our QA Manager cited our formal ethical policy so we took it on in the knowledge that from the information we had out the outset it would likely result in us losing forever a supplier and a possible future customer. We placed a large one-off order for hose fittings then went ahead ... so we enter the territory of large NREs for custom 18mm pillar valves ...
Thanks to Paul: I will give you a call early this week to follow up, if you are interesting in supplying these valves, as well as call Faber again. Getting a corrosion resistant cylinder approved is a lot easier than making them corrosion resistant in the first place.
Cheers,
Alex
