Hayward SX200Z9 Drain Cap Gasket Replacement for Select Hayward Filter and Multiport Valve

They do what they're supposed to do...be gaskets for your Hayward Pool Filter; if you were expecting them to do something else you may be sorely disappointed.I could give a more detailed review, like how easy they were to remove from the packaging (and they were) or how the rubber they're made from seems to be very durable (it really does), but then I would just be trying to fill this review with gibberish to see how many people would read it and we all know nobody wants to spend their time reading gibberish! Unless you're still reading this, then you must be one of those who enjoys the finer things in life, such as reading gibberish filled Amazon reviews about replacement gaskets. So to you, I SALUTE YOU!
