Construction
Single wall: .016" or .025" stainless steel (all tees are heavy gauge .025").
Seam: Continuous seam welded.
Insulation: Optional (required for some applications) Foil backed ceramic liner.

Can be used either as an appliance adapter for stainless flex or to connect rigid EXCELiner to flex.
Note:  The male end of the EXCELiner will fit into most brands of stainless flex (except for some modes of flex which are intentionally made undersize) so no adapter is generally required when the flex is installed below the rigid.
