Fiberglass Gasket

Fiberglass Gasket (Not Included).

A fiberglass gasket is a pliable foam gasket that is made of fiberglass, a type of glass. These gaskets are used to seal two pieces of metal together instead of using a traditional gasket made of rubber. A fiberglass gasket typically lasts longer than a rubber gasket and can be more easily used in extreme temperature applications.

Fiberglass gaskets are resilient and can withstand exposure to harsh chemicals, extreme temperatures, and ultraviolet light. Used primarily in HVAC and indoor plumbing systems, they may help provide a water-tight seal to prevent leaks from the drain pipe. Why is a gasket used? A gasket is placed where two surfaces must be held tightly or sealed together for an airtight or liquid-proof seal, such as in plumbing, air conditioning, refrigeration equipment, and more. Gaskets are available in varying durometers to match any application.

This fiberglass gasket is made specifically for the 18-21 Series Air Conditioner. This product is a high quality replacement part that will keep your system operating at maximum efficiency and performance.
