Thanks, HWY396ghost.
I don't know how I missed your post when I searched.
Angle flange was the term I was missing.
A couple of questions:
- How do you connect the hose to the flange? My hose is 3.13" inside diameter, so won't fit through a 3" fitting.
- What material are you passing through? I'm going through aluminum siding, 3/4" polyiso, .2" wood paneling. My concern is the heater hose being too hot and needing a small air gap (a la double wall pipe for stove).
Thanks again.
Looking back at my photos and narrative, I just realized how incomplete the description is… my mind was filling in the blanks.
The angle flange passes through (from interior to exterior direction) a layer of “coin” flooring, 3/4" plywood, then the E250 floorboard. The flange is secured with screws from the interior side.
I have a Planar portable diesel heater that sits outside the van, on the ground, when in use. Separate fittings are used to secure the interior hose and the exterior hose to the angle flange. Fortunately, Planar offers a variety of hose couplers, adapters, and reducers in different diameters.
A Planar coupler, built up with a few wraps of heat tolerant tape, fits snugly into the exterior end of the angle flange for a friction fit that works great. The coupler is connected to a Planar hose adapter; the two are held secure with a couple of ring pins. The hose adapter is connected to the Planar heater hose.
On the interior, a Planar coupler fits perfectly into the angle flange opening, after the detents have been filed off.
Hope that helps.
