The Dometic ST Series Sealing Ring is a critical gasket component that maintains an airtight seal on Dometic ST refrigerator doors. This replacement ring prevents warm air infiltration and refrigerant loss, ensuring your RV fridge operates at peak efficiency. If your refrigerator isn't holding temperature or you notice frost buildup around the door, a worn sealing ring is often the culprit.

Frequently Asked Questions
How do I know if my sealing ring needs replacement?
Signs include visible cracks or hardening in the rubber, frost buildup inside the fridge, difficulty closing the door, or the fridge not maintaining temperature. If the ring no longer springs back when pressed, it's time to replace it.
Is this ring compatible with all Dometic refrigerators?
No—this ring is specifically designed for Dometic ST Series refrigerators. Always verify your model number before ordering. Check your fridge's nameplate or owner's manual to confirm compatibility.
Do I need professional installation?
No. Most RV owners can replace the sealing ring themselves in 10–15 minutes. The ring typically pulls out of a groove around the door frame and snaps back in. Consult your refrigerator manual for exact removal steps specific to your model.
