We recommend the use of silicone grease to bed in the spider gasket rather than adhesive.
Please note that it is quite common for Midas tops to be fitted on Hayward bodies. This may cause a problem with the spider gasket . Please check the body for any marks which would show that it is a Hayward 710 rather than a 710X which uses the same spider gasket as the Midas. If you are unsure ,please order a 6 legged gasket which can be modified to 5 legs if necessary.
If it is simply a Hayward 710 this uses a 6 legged spider gasket which can be ordered here.
