Yeah its the pins and the metal plate at the bottom but the gas shouldn't even be getting there if I'm correct? What's the size of the big o ring as i could probably get them much cheaper than £15
No idea. Maybe measure the old one? You could easily get a single pack for a couple of quid, but I added up all the bits and frankly at those quantities you actually save money. A lot of people use a generic o-ring kit, but that isn't always the solution.
