I'm trying to source a vacuum cup used on a Japanese built machine. The basic description is: –
1.5 Bellows, Silicon
4mm Diameter hole to fit over barb on level compensator
Dimensions are critical
try PIAB B8.20.01AB very close
try Convum. In Belgium it is part of Parker but I don’t know if this is wordwide.
You may try ACY vacuum cups, they have a lot series of vacuum cups for Star, Yushin, Harmo and also for holders. The website is “www.acy.com.tw”
