Thread: Using 1/4" olives on 6mm nylon air line - will they seal?

I'm no expert but I would go for the correct 6mm ones. Just my opinion

You can get away with it if you use the internal ferules that fit inside the hose, this prevents the hose from collapsing and allows a little more pressure to be applied by the nut onto the olive, but be careful, as it is easy to split the nut if over tightened...... as our apprentices at work keep finding out

my only experience is with swagelock fittings and yes they do seal...

I would go to a seller of european brand pneumatics, e.g. Festo.

Also if you have a gas conversion place nearby, ask if he has any as some european LPG equipment comes with 6mm olives for their copper tube connection, they aren't used in Australia as we have to use 1/4 flared tube fittings.

Most pneumatics companies (including Festo) don't make olive type fittings. The company I work for have them in their range but we don't carry much as there is virtually no demand for them for general pneumatics use. They're still used in the truck industry and also on centralised greasing systems.
I know a local company that carry them but not sure about metric sizes.

Scouse, what size is the thread you are screwing the fitting into ?
I guess the other question is why do you want to change from push fit connectors ?

Are olive fittings a perfect, 101% seal compared to the push-fit 99.99999999999% integrity ???

- Certainly would appeal to the Puritan work-ethic.... much effort & expense yielding rightous satisfaction in a job well-done, as opposed to the sinful easiness of a push-fit...

Is the (Imperial) 1/4 flared fitting actually specified ? Or just a flared fitting...

Interesting if it is. - size-wise, I mean. I've always understood screw-up fittings to be the best possible seal, and most reliable regarding catastrophic failure.

Swagelock fittings when used with nylon must use an insert also. Other wise you are asking for trouble if you operate them at their potential pressure.
