Product details

Part R0337600 is the header coupling o-ring for Jandy Laars LX and LT pool heaters. It seals the coupling joint where the header sections meet.

What it does

The header carries pool water across the top of the heat exchanger, and the coupling joint sees full system pressure every time the pump runs. The o-ring is the only thing between that pressure and the outside of the heater, so when it goes the symptom is water tracking down from the coupling.

When to replace

Any time the header coupling is taken apart, and any time there is a leak at that joint. Rubber in a heater header goes through constant heating and cooling, which hardens it and leaves it compressed in the shape of the groove. Once it has taken that set it will not seal again, even reassembled carefully.

Before you order

The part is listed as a header coupling o-ring and is also described as an o-ring set. Count the seals your header coupling actually uses so you order the right quantity.

Questions and answers

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

Which heaters does this fit?
It is carried under the Jandy Laars LX and LT heater parts.
Is this one o-ring or a set?
The listing name is singular and the source description calls it a set. Check the header coupling on your heater for how many seals it takes before you order.
Where does it sit?
At the header coupling, the joint between the header sections on the heater.
Why would it fail?
Heat cycling. The rubber hardens and takes a permanent set over many heating and cooling cycles, and once it no longer springs back it stops sealing.
