Astralpool Multiport Valve Diverter Stem O-Rings, Pair - Top Mount Valve - 75062

• Physically Stocked, unlike most "drop-shipping" websites.
• Shipped from VIC, NSW, WA, QLD

Genuine Astralpool o-rings for the diverter stem of Astralpool and Hurlcon top mount multiport valves. 75062 is supplied as a pair, because the valves that use it carry two of them on the stem, and both should be renewed together. Astralpool lists it as the o-ring for the top mount valve diverter stem, No. 10 on the Multiport Valve parts list, and it is also sold as the diverter o-ring set, rotor o-ring, stem o-ring set and back ring o-rings. The Astralpool spare parts number is also written as SP75062.

These o-rings seal the stem where it passes through the valve, which stops water weeping out around the handle. Water at the rim of the cover is a different o-ring, and water running to waste while the valve is on Filter is usually the spider gasket. Use the rule below before you order, because the single stem o-ring 75905 covers the same position on other valves.

The Two or One Rule (rev. MPV-STEM-PAIR-1.0)

Astralpool shows No. 10 differently depending on which parts list you are reading. This is the single most common mix-up on these valves, so check the diagram for your own valve before ordering.

1. Find the exploded diagram for your valve, not for your filter, then look at position No. 10 on the diverter stem.
2. Two o-rings shown at No. 10: you need this pair, 75062. The Multiport Valve, Sep 09 to Current parts list is drawn this way.
3. One o-ring shown at No. 10: you need the single shaft o-ring, 75905. The 50mm 76053 and 40mm 76036 valve diagrams are drawn this way.
4. Diagram unclear, or the valve is older than you can date: pull the cover off, count the o-rings on the stem, or send us a photo of the stem and the valve and we will confirm which one you need.

Turn the pump off and release the pressure before you remove the valve cover.

Fitment

This set suits the valve, not the filter. An older filter may carry a newer valve and the reverse, so always check the valve itself. 75062 is listed for Astralpool and Hurlcon top mount multiport valves in both 40mm and 50mm, on the parts lists that show a pair of o-rings on the diverter stem, including the Multiport Valve, Sep 09 to Current list and the 40mm multiport valve diagram covering the RX, FG and E Series.

Supplier listings for this part disagree on the valve era. Some list 75062 against post September 2009 valves, others against pre 2007 valves. The reliable test is the diagram and the stem itself, not the year. Count the o-rings on the stem, or send us a photo and we will confirm before you buy.

If your valve takes a single stem o-ring, order 75905 instead.

When to Replace

Replace both o-rings when water weeps from around the handle or stem with the pump running, when the handle feels stiff or notchy, or when the old o-rings are flattened, cracked or hardened. Replace them as a pair even if only one looks worn. Fitting them means taking the cover off the valve, so it is worth doing whenever the cover is already off for a spider gasket, diverter or spring service. Clean the stem and the grooves before the new o-rings go on.

Frequently Asked Questions

How many o-rings come in 75062?
Two. The valves that use this part carry a pair on the diverter stem, and both should be replaced at the same time.

What is the difference between 75062 and 75905?
Both sit at No. 10 on the diverter stem, but on different Astralpool parts lists. 75062 is the pair shown on the Multiport Valve, Sep 09 to Current list. 75905 is the single o-ring shown on the 50mm 76053 and 40mm 76036 valve diagrams. Check your own valve's diagram, or count the o-rings on the stem.

Does it fit both 40mm and 50mm valves?
Yes, it is listed for Astralpool and Hurlcon top mount multiport valves in both port sizes, on the parts lists that show a pair at No. 10.

Water is leaking from the rim of my valve cover. Is this the part?
No. That is the cover o-ring, 75919 on a 40mm valve or 75930 on a 50mm valve. 75062 seals the stem at the centre of the valve.

Water runs to waste while the valve is on Filter. Will these o-rings fix it?
No. That is an internal leak, usually a worn spider gasket (75916 on 40mm valves, 75929 on 50mm valves) or a weak spring (75912).

My valve handle is stiff and hard to turn. Is that these o-rings?
Often. Hardened stem o-rings make the handle stiff. Check the spring washers and the spring while the cover is off, since those wear at the same time.

Is this a genuine Astralpool part?
Yes. We are an authorised Astralpool and Fluidra dealer and warranty agent, and this is the genuine Astralpool 75062.
