The 80mm vitreous enamelled silicone gasket is an essential accessory for ensuring maximum airtightness and safety in flue gas evacuation systems. Designed specifically for pellet stoves, fireplaces, and metal flues, this gasket ensures that combustion gases and smoke are properly channeled to the outside without risk of leaks into the home. Its high-quality composition offers excellent thermal resistance, withstanding the demanding temperature conditions typical of biomass heating.

During the operation of a pellet stove or fireplace, the correct connection between the different sections of pipe is vital for maintaining optimal draft and the appliance's energy efficiency. This 80 mm gasket is easily installed at the joints of the vitreous enamelled flues, acting as a flexible and airtight barrier that absorbs the minor thermal expansions caused by ignition and shutdown cycles. Thanks to its durability, it becomes an indispensable replacement part for the preventive and corrective maintenance of your heating system.

Frequently Asked Questions about Pellet Stove Gaskets

When should the pellet stove gasket be changed?

It is recommended to check the sealing gaskets at least once a year, coinciding with the annual cleaning and maintenance of the chimney or stove. If you observe signs of wear, cracks, loss of elasticity, or if you notice a smoky smell near the pipe joints, you should replace them immediately with part number B25023650.

Is this gasket compatible with any 80mm tube?

This gasket is designed to fit the 80mm vitreous enamel flue systems and pipes used in the vast majority of pellet stoves on the market. Be sure to check the diameter of your flues before installation to ensure a perfect fit.

Is any additional sealant required for installation?

The silicone gasket itself is generally designed to provide a pressure-tight seal within the pipe joint system. However, in certain specific installations or as specified by the pipe manufacturer, it may be compatible with special high-temperature sealants or mastics.
