Notice: Due to damage caused by Hurricane Harvey to the petrochemical facilities in Texas, plastic pipe prices are extremely volatile and availability may become an issue. Prices shown on our site are for our current stock and subject to change. We reserve the right to limit quantities or cancel orders. This effects all types of plastic pipe and tubing.


Gastite® Corrugated Stainless Steel Tubing (CSST) with Flashshield can be used to supply natural gas or LP gas to appliances. It is a reliable, cost-effective system that can be installed in new construction or remodeling jobs.  The tubing consists of Type 304 stainless steel with a UV resistant polyethylene jacket.  It is flexible and durable enough to route through building structures. The tubing also has foot increment markings on the jacket for ease of installation.
