Astral / Hurlcon O-Ring for MPV Valve to Tank Seal – 40mm & 50mm (SKU 75058)
🏷️ Brand
Genuine Astral / Hurlcon spare part.
📝 Description
This is the O-ring that seals the multi-port valve (MPV) to the filter tank on Astral and Hurlcon sand and glass media filters, fitting both 40mm and 50mm valve sizes.
Over time this rubber seal can perish, harden or compress, which lets water leak out between the valve and the tank body — replacing it is a simple, inexpensive fix rather than needing to replace the whole valve.
