Custom Gaskets for HVAC


Recommended Posts

Fitting went well today! Everything other than the evap seal mates up well. I made the end piece of the evap seal a bit too large to poke through the hole, easy fix. The blower motor seal also has a slight gap at the top, may have to add just a bit of thickness to it or perhaps it will close upon tightening the nuts on the firewall studs. Will be cinching that down tomorrow (or the next time when it's not raining) to check and see.

Fills up the gap nicely!

The view from my fresh air intake. That hole the PO cut is at least useful!

Evap seal. Couldn't get it to fit with the heater box, shoved it in by itself. Will be trimming to fit this week at work. Besides the outermost piece being too large it fits like a glove.

Blower motor. You can see a bit of a gap above the firewall stud. I'd imagine this will close when the nut is added and tightened. Will be experimenting with that ASAP. If it doesn't close the gap I'll add some more beef to this seal and try again.

Made a few more changes and it looks like everything is working as intended!

New evap seal, added an insert for the vacuum grommet

Good on this end as well

After tightening up the nuts on the studs the blower motor seal fit nicely

Alrighty so after many test fits and redesigns here are the final products.  What do y'all reckon would be a fair price? I've found you can still buy the 97+ Cherokee ones, those are $60-80.

Hard to say what a fair price is from the purchaser side. Especially not knowing the amount of time you have invested. I have a feeling you can set your price anywhere you feel comfortable. People will buy or they won't. Good chance you sell several since we are all wanting your product.

Seriously though, definitely cover the costs of the material to make them.  And throw in a reasonable amount to cover your time at least.  Start with that as a baseline and see where you are.  Throw out a price and I bet many people will jump on it.

Will you be selling then individually or as a set only?

I could certainly do both, as people like yourself won't be needing the evap seal unless I can make one that works for you

Put in an eBay order for both of these - going to try and recreate them as well! I looked at several different heater boxes and these two + the one that I've already made seem like all of the variants.

Wanna put an AMC logo on those? Haha.

I don't see why not! If it works once I test the rubber out I'll need to get some that already have that logo

I'm assuming the most recent one I made (reply above) matches your original, yes?

To be clear, this is not original to my 1990; the evaporator is from a later model XJ... But yes, it looks like this

Alright, after working with A-Man a bit I've come to the realization that I'm going to need some test fitters. I'd like to get one from every year of Comanche, and Cherokee too (96 and below). Ideally getting feedback within a month, seals and shipping on me.

Shoot me a PM with your year model(s) if you're interested and I'll choose a random person with each year model. I'll draw the names next Friday, 8/9/2024.

I should clarify. I don't anticipate many issues, though I do want to try and cover all of my bases. I'd like to have feedback roughly by the end of September. The seals are easy to install, removal of the dash is as difficult as it gets.
