Genuine replacement body for the Astralpool 40mm multiport valve. The body is the main casting that carries the port connections and the sealing face the spider gasket seats against.

Before ordering a body, check the maths. Once you add a spider gasket, diverter and the labour to strip and rebuild, a complete valve is often the better buy. We are happy to price both ways - contact us before you commit.

Which Multiport Valve Part Has Actually Failed?

A complete valve is rarely the cheapest fix. Match the symptom to the part before you order:

Symptom	Usual part
Water running to waste while set to Filter	Spider gasket 75916
Handle cracked, snapped or spinning freely	Handle 75903
Handle will not hold or return to position	Spring 75912
Sight glass cracked, clouded or weeping	Sight glass 75906
Pressure gauge dead, fogged or reading wrong	Pressure gauge 75043
Diverter worn where it rides on the gasket	Diverter 75902
Top cover cracked or distorted	Top cover 75901
Valve body cracked or leaking from the body	Body 75900

Check the Age of Your Valve

Astralpool changed the 40mm multiport valve in September 2009. Parts are not interchangeable across that change. The quickest check is the spider gasket: the post-2009 valve uses a 128mm outer diameter, 4-spoke gasket. If yours does not match that, you have a pre-September 2009 valve - send us a photo and we will confirm what fits before you order.

Frequently Asked Questions

Is it worth replacing the body rather than the whole valve?
Often not. By the time you add a spider gasket, diverter and labour, a complete valve can cost about the same. Contact us and we will price both options for your filter.

How do I know if I have a post-2009 valve?
Check the spider gasket. The post-September 2009 valve uses a 128mm outer diameter, 4-spoke gasket. If yours differs, send us a photo before ordering.
