You’ll want to use this part when installing a Webasto heater when there is already a subfloor (such as plywood) in your van such that you cannot install the heater directly onto the van’s factory metal floor. It’s basically a metal sleeve that fits into the 4” hole you cut through the floor during your standard installation. Then you seal the sides of the sleeve into the floor hole with RTV or similar (your choice of product – not included with the kit) and it stays there separate from the heater, so heater installation/removal is not affected. This seals and protects the edges of the floor and is particularly good at helping prevent delamination of materials due to exposure to the open atmosphere from moisture, road debris, fuel leaks, etc.

The sleeve is installed through the 4″ hole and can protrude (hang down) below the van metal floor a bit. Ultimately the combustion exhaust and air intake hoses, wiring for the fuel pump and the fuel supply will go through this sleeve. The top of the sleeve would be flush with the top of your subfloor. Then you can install the heater with the included plate and gasket directly onto your subfloor on top of (over) the sleeve location.

About Vanlife Outfitters

Vanlife Outfitters started as a blog chronicling our founders' DIY camper van builds and has grown into a trusted one-stop shop for van conversion parts, curated by people who’ve built the vans and lived the vanlife ourselves. We only offer road-tested products we’d use in our own vans, and pride ourselves on fast shipping and world-class support. It’s not just about the gear - we provide expert-built guides, pre-purchase advice, and real support long after your order arrives. Built by vanlifers, for vanlifers, we’re here to help you build with confidence and enjoy the freedom of life on the road.

I’m happy to give a shout out to VanLife Outfitters. These folks are an incredible example of how a company should conduct business. Although I’m building a truck camper, I have bought several things from VanLife outfitters and their customer service is bar none . I would never hesitate recommending VanLife outfitters to anyone whether they are building a van camper or boat. And I might add even a tiny home. Everyone that I’ve talked to have been nothing but incredible. In particular, Jason in technical support was an incredible blessing to me. I had a problem with the Aqua Hot Gen 1 heater I bought from them. It was not the heater fault, but something I did. Jason helped bird-dog the solution and together we got it fixed. He stuck with me, did research, and called me back several times to make sure that the problem was resolved. These people know the business, many have their on rigs, which gives them the best experience. Thanks you Vanlife Outfitters!!!!

This company is amazing! Quick shipping, best price possible. Customer for LIFE! Thanks Vanlife!

My husband and I are doing our first vanbuild. As rookies, we have found Vanlife Outfitters to be a trusted resource for ease of product shopping and purchasing, video demonstrations, guidance and excellent customer service. They were particularly a great one-stop shop when building our electrical system.

I ordered most of the parts for my sprinter conversion from them. They have absolutely the best customer service. I had issues with my fridge installation duing the weekend and eamiled their customer service for help. Both times, they emailed me back with the instructions/help I need on Sunday. Thank you and this is absolutely my go to place.

Spent lotsa money here, will probably spend more. High quality products, fast shipping and tremendous support. Excellent free resources, e.g. wiring diagrams, on the website. Highly recommend.
