Watch as Jessica Gibson, of Preferred Sales, overviews Gastite FlashShield. Gastite FlashShield is a Corrugated Stainless Steel Tubing (CSST) gas piping system featuring a unique metallic shield layer between two polymer jackets, designed to provide superior lightning and electrical fault protection for natural gas/LP lines without requiring separate bonding, allowing for faster installation with specialized XR3 fittings that ensure electrical continuity and a reliable metal-to-metal seal. This multi-layered design dissipates electrical energy and heat, reducing damage risk and offering quick, flexible installation, often 30-70% faster than traditional methods.
