What Is Flak Jacket Arc-Resistant CSST?
Flak Jacket is Pro-Flex's arc-resistant corrugated stainless steel gas tubing product. Like traditional CSST, the tubing provides a flexible alternative to rigid gas piping and can be routed through building structures with fewer directional fittings than many black steel piping layouts.
The distinguishing feature of Flak Jacket is its proprietary black jacket. Pro-Flex states that the jacket provides protection by dissipating electrical energy and identifies the product as requiring no additional bonding beyond the applicable system installation requirements.
Flak Jacket CSST uses the same Pro-Flex fitting system as the manufacturer's Yellow Jacket CSST.
