How to Replace a Sliding Door Gasket

Learn how to replace the gasket on a horizontal sliding walk-in cooler or freezer door. This video provides a helpful overview of sliding door gasket replacement to help restore a proper seal between the door and frame in commercial cold storage applications.

The gasket is an essential part of a walk-in cooler or freezer door's sealing system. Over time, repeated door operation, temperature changes, and normal wear can cause a gasket to become damaged, torn, compressed, or deteriorated. When the gasket no longer seals correctly, cold air can escape while warm, humid air enters the refrigerated space.

Replacing a worn or damaged sliding door gasket can help restore consistent contact around the door opening and improve the performance of the cold storage door. An effective seal can help reduce air infiltration, condensation, frost and ice buildup while minimizing unnecessary demand on the refrigeration system.

After gasket replacement, proper door alignment and gasket contact are important to achieving an effective seal. Inspecting the gasket regularly and addressing damaged or worn sealing material is an important part of preventive maintenance for horizontal sliding cooler and freezer doors.

This video is a useful resource for refrigeration technicians, facility managers, maintenance personnel, contractors, and cold storage operators who need to replace a gasket or troubleshoot sealing and air-leakage problems on a horizontal sliding walk-in cooler or freezer door.
