Modular Link Seals
Modular mechanical seals built from interlocking rubber links with bolts and pressure plates. Tightened in the annular space around a pipe penetration, they expand to form a hydrostatic, gas- and water-tight seal.

Questions & Answers
What is a modular link seal?
A modular link seal is a chain of interlocking rubber links with pressure plates that is wrapped around a pipe inside a sleeve or cored hole. Tightening the bolts expands the rubber to fill the annular space, giving a hydrostatic seal that also absorbs vibration and minor movement.
What is the difference between a link seal and a puddle flange?
A link seal is mechanically tightened into the annular space around an existing pipe, so it can be installed or replaced after the wall is built. A puddle flange is fixed to the pipe and cast into the concrete, so it must be in place before the pour.
What fits do you supply for modular link seals?
Annular space in a sleeve or cored hole. Other sizes can usually be supplied on request — send your requirement for confirmation.
What materials are offered?
EPDM / nitrile links, steel or composite hardware.
Is a technical datasheet available?
Yes — the official YTM Pipe datasheet with dimensions, materials and standards can be downloaded on this page.
