Frequently Asked Questions

Q: How do I know if my roof gaskets need replacement?
A: Look for water stains on ceiling materials near AC units or vents, soft spots in the roof, or visible cracking/hardening of existing gasket material. Preventive replacement every 3-5 years is recommended.

Q: Will this kit work on my specific RV model?
A: This OEM Dometic part fits RVs with Dometic roof-mounted air conditioning and standard roof vents. Verify your AC model number matches Dometic specifications before ordering.

Q: Do I need to remove the AC unit to install this gasket?
A: Depending on your RV's design, you may need to partially disconnect or unbolt the AC unit to access and replace the gasket. Consult your RV manual or contact our support team for model-specific guidance.
