Hi folks,
I have a Prestige Hi-dome Aluminium pressure cooker which has done a good few years sterling service. Recently I noticed the component which supports the weight set (called I believe the weight support!) was slack. I took it apart before I tightened it and noticed what appeared to be the flattened remnants of an o-ring (on the outside of the pressure cooker) between it and the top of the dome.
I have tightened it up again and all seems well but I assume this o-ring has worn out and requires replacement. I can't find this part listed anywhere on the net (please note I'm NOT referring to the gasket for the lid seal). Does it have to be a special o-ring to resist the heat/steam/pressure, or can I use one from one of my many tubs of "useful things I never threw out in the hope of finding a use for one day" :-)
Thanks for any help,
Nigel
