Available in both a rigid and flexible form with s/s Jubilee clip, made from strong polypropylene and TPE respectively, these top hats are durable and lightweight. With low permeability to hydrocarbon substances and vapours, and high puncture and tear resistance, these are ideal for making an effective gas-tight seal and preventing damp ingress for applications in which a 110mm pipe penetrates a membrane. Top hats are ideal for use for when a pipe enters an attenuation tank and other applications where a 110mm pipe comes up against a perpendicular surface, and are suitable for use with jubilee clips or bonding tape.
