What should be done with a worn gasket?

A worn gasket should be replaced to ensure proper sealing and functioning of the system it is part of. Gaskets are critical in preventing leaks between two surfaces, and when they are worn, they lose their effectiveness. A compromised gasket can lead to fluid or gas leaks, which may cause safety hazards, reduce efficiency, or lead to costly damage to machinery or equipment.

Repairing a worn gasket is not typically a viable option because most gaskets are made from materials that do not lend themselves well to effective repairs. Sanding down a gasket can potentially create an uneven surface or alter its thickness, further reducing its sealing capability. Leaving a worn gasket as is can result in significant operational issues. Therefore, the most reliable course of action is to replace it with a new gasket that meets the specifications required for the application. This approach ensures the integrity and efficiency of the equipment.
