Does anyone know the size of the 0-ring on the waste tank cap?

The last time I pumped out the o-ring on the cap fell into the water.

Need to buy a new one.

    X2 on West Marine. I replaced my fuel cap o ring on my old 232 and my new 280. They are made by Perko.

    I carry an extra cap with me as I saw a kid at a pump-out station drop a guys cap into the water last year. I keep it in a zip bag with the "key" for the cap. You get two caps in the parts container from Perko. MT

    The fuel o-ring is larger cross-section diameter than the water/waste o-rings.  I have the info at the boat and can pass it on tonight, I want to say one is a 1/8" dia the other 3/16"  Both butyl-n material, if you can find the gas one in Viton it is worth the few extra bucks.
