A/C Delete - How to plug hole in Firewall?

[Panici]

Finally got around to removing the A/C hoses running through the firewall.


Any suggestions on how I can block this hole into the cabin? I took a quick look at RealOEM and didn't see anything that fits.



Cheers!

Tons of ways.

Fiberglass.
Steelstik.
Hockey puck.
Take a mold of it and make a urethane plug.
Clay.
Dirt.
Grass.
Rivet a piece of metal on.
Tack a piece of metal on.
Spray foam insulation.
Rigid foam insulation.

The sky's the limit man. Go nuts.

Take dimensions and have someone who does CAD draw one up and 3D print a plug out of TPU.

I have to thank Jacob Falk from the R3V facebook group.
He saw my post and designed and printed a plug for me, in record time!
I love our enthusiast community!


I used some sealant for good measure when I installed, but i'd say it would keep the water out without it.
Fit is fantastic, and it's fully reversible if I want to run A/C again. Reasonable price as well.

It's also a soft/pliable rubber material, could drill a hole through it and run wires if needed.

https://www.falkmfg.com/ is his website if you need one!

Thread update:

I ended up welding in a patch for the hole.
The plug worked great, I just wanted a cleaner solution for my semi-shaved engine bay.
