Spare Catalyst Lid Seal

It was what I ordered.

My old lid was not sealing after I dropped it and cracked one of the clips. With the new seal, my new lid seals like it was new and bubbling through the air lick like it is supposed to.

Good fast service. Having said that, I wish that in the scant users instructions that came with the Catalyst system, there would have some basic information about the care and cleaning of the seal, and have a recommendation to always have a spare.
