Top Hats are pre-formed pipe seals that are manufactured in various diameters to provide a bespoke pipe seal to suit the outside diameter of pipe penetrations through any Landflex gas membrane. The top hat should be welded or sealed to the gas membrane using either hand held welding or our Landflex self-adhesive gas membrane. The top hat should be secured to the pipe either with a ‘jubilee’ clip or with additional wrapping of Landflex adhesive gas membrane.
