Abstract
Thermal insulation for the piping of a sink or the like comprises an elongate tubular piece that is fabricated from a resiliently yieldable material and that has integrally formed, resiliently yieldable internal rib formations projecting into the passageway through which the piping extends. The rib formations enable more universal application to pipes of various sizes, while also affording better insulating and cushioning properties. Angle valve piping insulation includes a hinged cover component that is normally at least substantially closed, and that is readily displaceable to permit access into the internal body passage.
