Kindle Customer –
Did not work on a Dometic model 210. The size was too large to rotate. Right part number, but a very bad fit.

Do not buy!!! I have a Dometic Sealand Toilet Model 148, which this is recommended for. These parts do not fit properly. The ball rubs and the shaft (with seals) are oversized and do not allow the ball to freely rotate. After several attempts, I finally ended up installing one of the shaft o-rings on my old shaft and reusing the old ball. I did also use the new spring actuator although my old one was still good. That part seemed to be OK. If you have a vacuum leak, just buy replacement o-rings at the hardware store for about 30 cents each and be done with it. This was a $20 POS mistake
