Frequently Asked Questions

How do I know if this o-ring needs replacing?
If water is leaking from the joint where the multiport valve connects to the top of the filter tank, the valve-to-tank o-ring is the most likely cause. Inspect the o-ring for cracking, flattening, or deformation.

Is this a genuine Astral Pool part?
Yes. Part No. 75058 is a genuine OEM Astral Pool / Hurlcon replacement o-ring, not an aftermarket substitute.

Will this fit both 40mm and 50mm valves?
Yes. This o-ring suits both 40mm and 50mm Astral multiport valves on E-Series, FG, and RX filter models. If you are unsure of your valve size, check the label on the multiport valve body or contact us before ordering.

Do I need to drain the pool to replace this o-ring?
You do not need to drain the pool, but you should turn off the pump, close any isolation valves, and depressurise the filter before removing the multiport valve. Always follow safe maintenance procedures.
