Or you can get a 1 1/4" leather cup washer/pump seal for a few quid off the bay that should fit ok with a little persuasion - item No. 324686903414 for instance (two for £7.25 inc delivery)
HTH,
Dave
p.s. if you want to have a go at making your own I can let you have some veg tanned leather in a few different thicknesses, ideal for the purpose...
