DVM E61 Silicon Group Gasket Set 8.5mm set  €8.99

Details:

This 8.5mm version suits E61 machines over 2 years  - we have an 8mm version for newer models - see below.

This contains 2 heat-resistant silicone gaskets and a paper shim in case the portafilter slides to the right. Silicon lasts longer, this makes a big difference in a busy environment.
The internal groves and soft consistency make for easy installation and removal and the light color helps to detect if there is a build-up of coffee debris 

If you notice that there's water leaking from the area above the portafilter, known as the group head, then your gasket is probably to blame. When changed your coffee cream will improve as you will have achieved the maximum extraction pressure of 9 bars. (The pressure will be constant as the filter basket has a full seal.)

Contents:

• 2 x  silicon Group gasket   
• 1 x Paper shim - - this will prevent the portafilter from sliding to the right if the group/portafilter is worn. 

Features:

• Better than rubber gaskets, since silicone doesn't have any smell or taste and is easy to change in and out.
• The light color helps to detect if there is a build-up of coffee debris.
• Easy to install - just push on and lock with the portafilter.

Gasket change

• Commercial replace every 6 months,
• Home          replace every 12 months 

The longer you leave it the more difficult it will be to remove them. The group seals become brittle over time due to heat from the portafilter and with age. When removing the old one it will probably fall apart as it will be so brittle. We recommend that you always keep spare gaskets.
