    Introduction to Ring Seal

    Ring Seal is a professional air and watertight seal for when pipes pass through walls, floors or ceilings. Ring Seal is used to seal pipes and cables passing through solid structures and are suitable for either a cored hole or pipe sleeve application.

    Ring Seals offer a professional finish, with simple, fast installation. The system is made up of linked modules which when tightened form a compression seal.
    This also prevents temperature and noise transfer.

    The product comprises a rubber EPDM seal with a front and back plate, the nuts are tightened pressing the plate into the rubber and expanding uniformly outwards to give an air and watertight seal.
