Buy a replacement gasket for your Wega, Expobar or Rocket espresso machine, or any other espresso machine with an E61 group head. This gasket is designed for use with any E61 group head, so it's a perfect fit for many of the top espresso machine brands on the market.

This particular gasket is made of silicone, rather than rubber. Silicone gaskets are newer to the market but are believed to form better seals and to last longer than their rubber counterparts.

Gaskets generally need to be replaced when they wear out. You'll know it's time to replace your group head gasket if you see any leaking from the group head while brewing. In a commercial setting, you should replace your gaskets at least every 6-12 months.
