Replaced a worn out gasket. Silca presto head works as good as new.
This rating is probably confused with a general rating of Silca pumps. The design of Silca products allows for replacement of any parts as they wear to extend the lifetime of the pumps. This design has kept my Silca going for 22 years. This gasket is probably the tenth in that time. The pump sees very regular use. Daily and often by multiple users at club rides.
It fits exactly where it's supposed to be and works well
Didn't seal. Gage needle dropped as quickly as the pressure stroke raised it. Went back to large rubber washer, which worked just fine. Maybe I didn't give it enough chance, but if it's still in the junk parts box when I'm out of rubber washers I'll try it again.
Every 5 years i replace it, simple and reliable.
