Door gasket Tefcold SpareParts 12051

A flexible door gasket maintains the airtight seal between the cooler door and cabinet, blocking warm air from entering and cold air from escaping. Each time the door closes, the rubber or silicone strip compresses against the frame, creating a barrier that stabilises the internal temperature and reduces strain on the refrigeration system.

To replace the gasket, the operator removes the old strip by pulling it from the retaining groove around the door perimeter. The new gasket is pressed into the same groove, starting at one corner and working around the door until the seal sits evenly. The door is then closed and checked for gaps; any unevenness is corrected by adjusting the gasket within the groove.

This gasket is a direct replacement for the Tefcold DB300H-3-P backbar cooler, matching the original dimensions and profile to ensure a proper seal without modifying the door or cabinet. It fits the retaining groove of the specified model, requiring no additional tools or adjustments for installation.

The material forms a continuous seal around the door, preventing temperature fluctuations that increase energy consumption and reduce cooling efficiency. Regular replacement of worn gaskets restores the original performance of the cooler, maintaining consistent refrigeration and reducing operational costs.
