The 70 x 59 x 0.8mm Card Padding Washer Shim is an essential maintenance component used in commercial espresso machines. Installed behind the group head gasket, it increases the effective gasket thickness, helping to restore a tight seal between the portafilter and the group head.

Over time, constant use can cause gaskets and group components to wear, resulting in poor sealing or excessive portafilter rotation. Fitting a padding washer shim can help correct these issues without immediately replacing additional parts, making it a practical choice during routine servicing.

Manufactured from durable card material, this shim is designed to withstand the operating conditions of commercial coffee machines while supporting consistent brewing performance.
