What Dometic Seal do I Need for My SeaLand Model 910 Toilet With Serial Number 340184?

Question:

Good afternoon! I have a 1986 Hi-Lo 2268d RV camper that Im refurbishing. I have a SeaLand Model 910 toilet with serial number 340184. This DOM35FR looks like an exact match. Would you have any information on my 910 model that would match this? Please ignore the dirty part in my picture. Thanks Norm

Hello again Norm,

Thank you so much for the picture, it is most helpful since I wasn't able to get any information off of the serial number. Yes, you found the correct one, the Replacement Toilet Bowl Seal Kit for Dometic Sealand and VacuFlush RV Toilets # DOM35FR is exactly what you need. I know this from your picture because of the hole in the seal, this tells me that you do indeed have the overflow hole in the toilet bowl. The older Sealand Model 910's have the overflow hole, and the newer ones do not.

If you were to shine a flashlight under the rim at the back of the bowl and look/feel you will see/feel a small hole/slot.

How are things coming along on the refurbish? Think you will have things ready for camping season?

Hello again Kate! Thank you si much! I double checked rim, and it's exactly as you described. I'm also going to replace the floor seal with DOM98FR now as well. I described my current adventure on a social media post this morning as constantly going down a rabbit hole. But the refurbish is coming along. I've just recently finished the interior ceiling, new water heater, and lights. Unfortunately, one of the lift cable lines broke. I'll be replacing that in a few weeks. We're planning on an October 2026 "launch".
