anyone understand olives?

I use the ordinary copper olives they definitely work provided you tighten them properly. I can't see the point of the bevelled edge, you would be crushing a small omount of metal against someting that won't crush. I'd be interested to hear if anyone uses them and why please.

The gas installation on the boat has copper olives AFAIK... but done long before I knew that copper olives were recommended


I would think just about all the domestic plumbing I have done in the house has brass olives.

Perhaps a similar application in the oilfield can help explain the difference. We use two styles of ring gasket on HP flanged connections bevelled and plain ring type.

The plain ring type is the least (but still good) reliable gasket. The ID seal is robust but the OD sealing force is spread over a larger area and so is less robust as it produces less sealing force at the contact point. The bevelled type seals in a similar manner as the ring on the ID but produces much higher loads on the OD contact points, therefore deforms more to fit the OD better and produces a more reliable seal on the OD side.

Perhaps this explains the two shapes, the plain ring in my case is an old design the bevelled rings were an improvement on this.

I was once in a remote part of Norway with a fractured fuel pipe and no olives to make a repair. I found a plumbers merchant, but how to explain what I needed with not a word of Norwegian? So I acted it out with my hands, drew a picture...this went on for some time. The man behind the counter turned to me and said, in perfect English, 'what you need is an olive!'

Your navigation is a bit suspect, it seems to me you must have been in Greece.
