Will this fit a Sealand 2010?

No, this is NOT the proper seal for the 210 or 2010. The proper seal for those models is the 385316140,

Will this fit a 300 series Dometic for RV?

I purchased one for my 300 series toilet and it fit quite well. A little bit of massaging was needed to completely install but once situated, it worked fine

Is this an OEM dometic seal or 3rd party?

Dometic thanks you for your question. This is a dometic seal. For further information, contact our support team at customersupportcenter@dometic.com.

Does this fit the Dometic 3400 electric model?

Dometic thanks you for your question. Unfortunately, the 385311658 flush valve is only used on the 300 series toilets. We have verified with our RV sanitation department and there is not a 3400 model currently in production. Can you please verify your model number and contact us at customersupportcenter@dometic.com for more assistance?
