Default Gascolator o-ring

My annual fight to remove and reinstall the gascolator bowl resulted in a split o-ring this year.

Living in the UK, it was not easy to identify and source a suitable replacement o-ring. After several attempts, I found that a ring with 50mm internal diameter and 4mm thickness was the nearest - obtained from Simply Bearings. It was even harder than usual to reinstall the bowl as the diameter may be a tiny fraction too big, and the material was less compressible than the original brown ring.

So, to minimise future difficulties please can anyone identify who can supply me with the proper replacement o-ring?

Not sure if the gascolator used on the RV-12 (blue anodized aluminum) is the same unit you have .... but if it is, I know Van's stocks the O ring and the fine mesh screen because I've procured those items in the past from Van's.
