Video Transcript for Lippert Waste Master Donut Seal Review

Hey guys, Zach here at Today, we're going to be taking a look at a replacement part for the Waste Master. This is going to be a donut seal. This is going to be just a rubber fitting that goes on the end of our Waste Master here. So we get a nice tight seal into our dump station. And see...

Let's say this one got damaged, we can just take this one off. It's going to be an identical fit to it. See, it's just going to be a direct replacement. It's going to slide right back on top.And we just have a little mock-up dump station here just to give you an idea. But it's going to just slide right down in there and we're ready to start emptying out our tank.

Now this is recommended to use with the Waste Master system, but I'll take this off and I'll give you some measurements. So you can see if it's going to work out for your setup. The inner dimensions, there are going to be two and three quarters of an inch. The outer dimensions on the outside there are going to be four and a quarter inches.And then I'll give you that one again, outside, it's going to be three inches. So this will be exactly like the factory one that comes on your Waste Master system, there is no difference there.

So this is going to be a really good way to get your Waste Master back up and running. But overall, this is a really durable, rubber seal that's going to be easily replaceable, if you happen to damage that. This is a really nice system. You don't want to have to buy the whole new thing again, but overall, that's going to do it for our look at the Lippert components, rubber donut seal for Waste Master..
