    SEALFAST Air Seals - Annular Seals custom seals
    The "SEALFAST™" Annular Seal is
    designed to test containment pipe
    penetrations.

    Custom Air Seals and Annular Seals

    Designed to solve the problem of individually testing (LLRT) of containment penetrations (NRC information notice 92-20). These seals are of a split design allowing for installation over a pipe and into a sleeve which it passes through. This product seals against the process pipe allowing the annular space behind the seal to be pressure tested through a port on the seal.
