I'm finally back on my Viair upgrade.

There's no room for it on the small ledge inboard of the EAS housing. I'm going to mount it remotely on the firewall and run a 6mm tube into the housing. Extending the wiring is trivial.

Can anyone tell me the correct name for the little brass ring INSIDE the little blue pipe we connect to the compressor? I know it's not an olive - wrong shape, it has a shoulder. More like a top hat. Is it a ferrule?

In plumbing terms we would just call it an insert.

I feel a bit of a knob for not googling first. I just like being on here! It also means anyone with a similar question can see the answer...

In air lines they call it a Ferrule. You order with ID and OD. In our case OD 6mm, ID 4mm.

I'll flag it up if it's the wrong size when it arrives!
