Ring for Attix 30 -
fits in a groove on the bottom of the motor head assembly and
makes a tight seal to the canister. This gasket should be changed
periodically to ensure a tight seal and optimum performance. If
you own an Attix 50 and want to use the smaller/lighter Attix 30
canister, you'll need to purchase this gasket ring and remove the
stock Attix 50 ring from the head assembly. See photo of the head assembly with the 2 separate grooves for the different sized gaskets.
