Furnace gaskets play a critical role in sealing combustion chambers and system components to prevent air or gas leaks. Our furnace replacement gaskets are built for durability and proper fit, helping maintain safe operation and peak efficiency. Find the furnace parts you need to restore secure sealing in your heating system.

For an HVAC system or furnace to work efficiently, it needs to be sealed in all the right places. Gaskets are the components that work to maintain the performance of your heating and cooling apparatus, by preventing the loss of cooled and heated air. Whether you're modifying your existing system, installing new ductwork, or replacing worn out parts, Furnace Part Source has a wide variety of gaskets to choose from to help you make the most out of your HVAC project.

The Gasket Catalog For Furnace Replacement Parts

The performance of HVAC systems is often tied to the condition of gaskets; for this reason, the Furnace Part Source keeps a broad range of gaskets, rings, and seals in stock. Our line of gaskets will fit boilers, viewports, burners, and other elements of HVAC systems. Following are just some of our most popular gaskets:

Carrier Discharge Valve 06EA504914

This is the stainless steel discharge reed valve gasket for Carrier compressors; it will also fit Bryant and Payne units. A few of our clients like to keep a few of these in stock since they often need replacement, but there is no minimum order requirement to get this part shipped.

Honeywell 901444

Do you know how some parts are harder to find than others? If you are familiar with Honeywell F76S water filters, the ones that remove debris and excess minerals at high flow capacity, you probably know that its gaskets are not easy to locate.

If you have customers with these water filter installations, you know that gasket replacement will be required at some point because sediment particles will eat away at the material. Honeywell 901444 gasket kits for the F76s water filters come in packs of 10 and are very affordable.

Johnson Controls 246-423

This is a rubber ring-style gasket that fits the V46 pressure-actuated valve from Johnson Controls, which can be found in many air conditioning compressors. This simple gasket is often ordered by technicians who realize that colleagues did not handle screwdrivers gently when manually flushing the valve.

In some cases, HVAC technicians have ordered an entire replacement for the V64 valve only to learn that it shipped without a gasket; this is because some suppliers keep the items separate and forget to pack them into a bundled order or simply because they ran out of them. At the Furnace Part Source, we make sure to keep plenty of these Johnson Controls gaskets in stock.
