Malcolm, the outer seal is the same as the pump piston cap seal but the inner seal is not one that lives it a pump. It's quite a small one.

Any O ring that fits will do for that but do please doubly check it's good for LHM before use by soaking it in a pot of LHM for a week or so and observing how it might deteriorate in that time. Generally O rings that are good for unleaded petrol or ones made of Viton will be OK.
