Product details

The Nature2 W13073 is the lid o-ring for the two piece locking ring cap. It measures 6-1/8 in. on the outside diameter, 5-9/16 in. on the inside diameter, and 9/32 in. thick.

Get the right one

Nature2 uses two different lid o-rings and they are easy to confuse. This one suits the two piece locking ring cap. The o-ring for the one piece lid is larger in diameter but not as thick, and carries the part number W13061. Check the cap on your unit before ordering rather than going by diameter alone.

When to change it

The o-ring is what keeps the cap sealed under system pressure. Once it flattens, hardens or takes a nick, water starts weeping from under the lid and no amount of tightening fixes it. It is a cheap part to keep on hand and worth swapping any time the unit is opened for a cartridge change.

Questions and answers

What people ask about this product, answered by our pool techs.

How do I know whether I need this one or W13061?
Look at the cap. This o-ring, W13073, is for the two piece locking ring cap. The one piece lid takes W13061, which is larger in diameter but not as thick.
What are the dimensions?
Outside diameter 6-1/8 in., inside diameter 5-9/16 in., thickness 9/32 in.
Why is water leaking from around my lid?
An o-ring that has flattened, hardened or split will not hold the seal any more. Replacing it is the first thing to try before chasing the cap or the body.
Is this the genuine part?
Yes. It is Nature2 part number W13073.
