Frequently Asked Questions

How do I know if my SVC AC gasket needs replacement?
Look for water stains on your ceiling around the AC unit, visible cracks or hardening of the existing gasket, or air leaks around the unit during operation. If your AC is losing cooling efficiency or you notice moisture inside, the gasket may be compromised.

Is this a direct replacement for my Dometic SVC unit?
Yes. Part# 3313107.021 is the OEM gasket designed specifically for Dometic SVC series rooftop air conditioning units. It installs directly without modifications or adapters.

How often should I replace this gasket?
Gaskets typically last 5-10 years depending on UV exposure, temperature extremes, and weather conditions. We recommend inspecting annually and replacing if you see cracks, hardening, or signs of leaking.
