Coleman-Mach 14x14 RV AC Roof Gasket 2-Pack | 8332-3301
Coleman-Mach 14x14 RV AC Roof Gasket 2-Pack | 8332-3301 — Product description
The Coleman-Mach 14 x 14 mounting gasket is the foam seal between your rooftop air conditioner and the RV roof. It's the genuine Coleman replacement, referenced 8332-3301, and ships as a 2-pack with a foam strip and two pads to keep the roofline watertight.
The Coleman-Mach 14 x 14 mounting gasket is the seal that lives between your rooftop air conditioner and the RV roof. It's not glamorous, but it's the part standing between the cabin and every rainstorm you park in. This is the genuine Coleman replacement, referenced as 8332-3301, and it ships as a 2-pack with a foam strip and two pads.
If you're pulling an old rooftop unit or installing a new Coleman-Mach air conditioner, you replace this gasket. Every time. The old foam takes a compression set after a season or two on the roof, and once it's flattened it won't seal the same way when you torque the unit back down. Reusing a tired gasket is how you end up chasing a water stain on the ceiling six months later.
The 14 x 14 opening is the standard cutout on most RVs, campers, and motorhomes, so this gasket drops right onto that footprint. It sits on the roof around the opening, the AC unit lands on top, and the mounting bolts from inside compress the foam into a watertight seal. Simple, but it only works if the foam is fresh and evenly seated.
A few tips from doing these: lay the gasket down clean, no old sealant or grit under it, and snug the mounting bolts in a cross pattern so the foam compresses evenly. Don't over-torque. You want the gasket squished to about half its height, not crushed flat. The 2-pack means you've got a spare on hand, which is handy if you run a second unit or keep one in the parts bin for next season.
This is a wear part, plain and simple. If your current AC is leaking at the roofline, or you can see daylight or feel a draft around the base, the gasket's done its time. Swapping it is a straightforward job with the unit off, and a fresh seal is cheap insurance against roof rot and a soaked headliner.

Frequently asked questions
What does this gasket fit?
It's built for the standard 14 x 14 inch rooftop air conditioner opening found on most RVs, campers, and motorhomes. It's the genuine Coleman-Mach mounting gasket, referenced as 8332-3301.
What comes in the pack?
It's a 2-pack, and it includes a foam strip and two pads. That gives you a spare on hand if you run a second unit or want one in the parts bin.
Do I need to replace the gasket when I swap my air conditioner?
Yes. Always reseal with a fresh gasket. The old foam takes a compression set on the roof, and a flattened gasket won't seal watertight when you torque the unit back down.
How does it actually seal?
The gasket sits on the roof around the opening, the AC unit lands on top, and the mounting bolts from inside compress the foam into a watertight seal. Snug the bolts in a cross pattern so the foam squishes evenly.
What is the 8332-3301 number?
That's the Coleman reference for this gasket. The manufacturer part number on the package is 8332A3302. Both point to the same 14 x 14 black mounting gasket.
Can I over-tighten it?
You can, and you don't want to. Aim to compress the foam to about half its height, not crushed flat. Over-torquing can distort the seal and stress the AC base.
