Flat Oring to suit olive oil tanks

A flat o-ring to suit olive oil tanks, made in Italy. Seals are the part that quietly decides whether a tank does its job, and a flattened or perished o-ring is usually what is behind a weep around the lid or a tank that will not hold. Replacing one is a five minute job and a great deal cheaper than living with the problem all season. Worth keeping a spare if you fill tanks each year and do not want to be caught out on the day. Match it against your existing seal before ordering.
