Frequently Asked Questions

How do I know if my spider gasket needs replacing?
Common signs include water leaking from the waste port when the valve is set to Filter, loss of filter pressure, or water bypassing the filter entirely. If the valve body and o-rings are intact, the spider gasket is the likely culprit.

Is this a genuine Astral/Hurlcon part?
Yes. Part No. 75916 is a genuine OEM Hurlcon spare part, not an aftermarket substitute.

Will this fit my multiport valve?
This gasket suits 40mm AstralPool and Hurlcon top-mount multiport valves manufactured from 2009 to current. If you're unsure of your valve size or model, check the label on the valve body or contact us before ordering.

Do I need any special tools to replace the spider gasket?
No special tools are required. The MPV top cap can typically be removed with a screwdriver or spanner. Ensure the filter system is powered off and depressurised before beginning any maintenance.
