    I need to connect a plastic pipe to my cast iron main drain line under the basement slab.

    I have read about mission couplers and looking at the Fernco website wonder if these are the couplers referred to here and elsewhere:


    Description from the website:

    AISI 304 Stainless Steel Shield

    AISI Stainless Steel Clamps and Screw Housing:
    Full size 9/16" wide bands and one piece screw housings are mechanically interlocked for strength. The wide clamp band provides enhanced sealing force.

    Specially Beaded Gasket:
    Unique beaded Neoprene gasket grips with superior holding and sealing power. Gasket conforms to ASTM C 564.

    HD-4000 Couplings:
    meet ASTM C 1277 and meet test criteria of CISPI 310.

    Thanks for any help,

    Most areas just the rubber ferncos without the band is code but you can install shielded no hub mission couplings underground.
