Witch’s-Hat Sleeve for an Existing Pipe

Conical vinyl witch’s-hat pipe sleeve with a flat brim

A witch’s hat fits around pipes or other existing fixtures that protrude through the tank wall into the tank. It is a conical vinyl sleeve with a flat brim, named for its shape.

The cone tip is trimmed in the field to create an opening slightly smaller than the protruding pipe. The kit includes the witch’s hat and HH66 glue.
