Description
Two parts meet at this spot – the valve and the filter tank. The O-ring between them is a rubber seal: once it softens, ages or deforms, water starts to drip. The original Mountfield ring has the exact size and profile for the Swing Plus series.

Why it wears out
The joint is taken apart during repairs, when the sand is replaced and for winter storage. Every opening puts strain on the seal, which loses its elasticity and stops sealing. The new ring sits tightly in its groove, so the connection stays dry and reliable.

What you gain
The size, cross-section and elasticity are chosen for the specific model, so there is no need to try similar rings. This avoids leaks that later lead to a more expensive repair. With the code noted down, you can be sure the part matches.
Replacement
Stop the pump and release the pressure in the filter. Remove the clamp, lift the valve, take out the old seal and clean the groove. Fit the new ring, put the valve back in place and tighten the clamp. Finally, check for leaks.
Tips for seals
It is a good idea to replace them preventively, for example before the start of the season. Lightly moisten them with water or a drop of silicone grease for pools before assembling. Do not use mineral-based oils, as they corrode the rubber. Keep spare seals in the dark, at room temperature.
How to make sure it is your part
Find the code of your unit (for example, starting with 3BTE) and compare it with the list above. If it matches, MT06111 is the right choice. If in doubt, send us a photo of the worn seal and the model of your filter. While you are disassembling, look at the surrounding parts too: it is sensible to replace worn ones at the same time.
The seal serves the joint between the six-way valve and the tank on Swing Plus 4 m3/h. More consumables are available in the filter and equipment parts.
