Corrugated Stainless Steel Tubing (CSST)

I Overview
CSST is a continuous, flexible, stainless steel pipe with a plastic covering. It is flexible and lightweight, and requires fewer joints than conventional black iron pipe.

II Applications
CSST requires much less time and labor to install than iron pipe, in part because it is flexible. This property also allows it to be pulled like electrical cable.

CSST can be used in new construction, although its advantages over iron pipe are more apparent in renovation.

III Equipment Options
CSST is available in sizes up to 2 inches. Some brands offer an additional lightning strike protection feature.
