The flat gaskets work best when used with the old o-ring still in place. The flat gaskets work on both heater and pump unions. The O-ring/ gaskets are flat gaskets with an o-ring molded on one side to hold them in place better. These are for heater fittings but they will fit some pump unions as well. |
