Key specifications

Choosing the right option

Before fitting a new gasket, clean the surfaces with a suitable cleaner such as Loctite 7070. For new form-in-place gaskets see Loctite 518 Gasket Eliminator Flange Sealant or Loctite 598 Black RTV Silicone Gasket Maker 95g.

Using it

Hold the can upright 25 to 30cm from the gasket area and spray. A heavier coat gives better performance.

Allow 5 to 10 minutes for the foaming action, then remove the softened gasket with a scraper or putty knife and wipe the flange clean with a rag. Repeat if necessary.

Before assembly, clean the surfaces with a suitable cleaner, for example Loctite 7070. After use, turn the can upside down and spray for 3 seconds to clear the actuator.
