How to Remove Gasket Material
Gaskets seal the connection between two rigid materials. The gasket material often lodges against one of the pieces entering the connection as it ages or becomes heated. Before installing a new gasket on the connection, you must remove the old gasket. Using the proper tools to remove the gasket will ensure no damage occurs to the gasket mounting flange. A damaged flange will cause leaks to form around the gasket, allowing air or fluids to bypass the seal.
Instructions
- 1
Place plastic sheeting over painted areas surrounding the part containing the gasket material. Secure the plastic sheeting to the area with pieces of duct tape.
2Apply a gasket remover to the gasket material. Allow the gasket remover to sit on the gasket for 30 to 45 minutes.
3Slide the flat end of a plastic scraper under the gasket material. Push the scraper forward using short strokes to lift the gasket material from the gasket flange. Wipe accumulated gasket material from the scraper with a rag. Scrape the flange until no large pieces of gasket remain on it.
4Apply additional gasket remover to the gasket flange. Allow the remover to sit on the flange for another 30 to 45 minutes.
5Wipe the remaining material and/or adhesive from the gasket flange with a rag. Inspect the gasket flange. Repeat the process of applying and wiping the flange until no sign of the gasket material remains on the flange.
