2.1 FlashShield™ System Description
a) e FlashShield™ Flexible Gas Piping System has been tested in accordance with the American National Standard for
Fuel Gas Systems Using Corrugated Stainless Steel Tubing, ANSI LC1. is standard lists performance requirements
for certification of CSST systems for use with all recognized fuel gases, including Natural Gas and Propane.
FlashShield is also tested and listed in accordance with ICC-ES PMG LC1024 and LC1027, listing criteria for protective
jackets on CSST.
• Metallically shielded CSST.
• Protective jacket/shield is electrically continuous through fitting joints.
• System uses corrugated stainless steel tubing (CSST) made of type 304 alloy, ASTM A240.
• An annealing process tempers the steel giving it added flexibility and ease of bending.
• FlashShield™ Flexible Gas Piping is suitable for use with elevated pressure systems. e ANSI LC1 standard rates CSST
for use at pressures up to 25 PSI.
b) e tubing is connected using special mechanical brass fittings designed specifically for FlashShield CSST.
• e jacket is clamped by the fitting thereby minimizing the risk of contact with corrosives and foreign material.
• e use of XR3 fittings in combination with FlashShield™ is required.
• XR3 fittings have standard NPT threads and may be used in combination with all approved fuel gas piping materials
with the pipe threads as the interface. System components such as manifolds, tees and stubouts may be fabricated from
other approved materials to be used with FlashShield™ flexible gas piping.
• e self-flaring fitting creates a one step, reusable, metal on metal seal.
c) e multi-layered jacket is extruded over the stainless steel tubing creating a flexible, protective covering. e jacket and
metallic shield are added features of the tubing and do not affect the flaring/sealing process.
• Integrated metallic shield between semi-conductive polyethylene layers.
• e jacket is engineered with thermal and UV resistant material making it suitable for outdoor use.
• e extrusion process creates a smooth outside surface; this surface greatly aids in pulling the tube through tight building spaces.
• Polyethylene jacket blend contains flame and smoke additives making it ASTM E84 25/50 compliant.
d) e corrugated stainless steel tubing system has a number of essential hardware and design differences from conventional
gas piping using rigid steel pipe and copper tubing. ese differences are described as follows:
• In many applications, the tubing is sized for individual gas appliance loads and is, therefore, usually small in diameter. e
tubing may also be installed in a parallel fashion from a central distribution manifold rather than a series layout commonly
used for rigid pipe systems.
• Corrugated Stainless Steel Tubing is pulled through the structure similar in fashion to electrical wiring and therefore
requires different handling and installation techniques than rigid pipe.
• Rigid termination of the tube ends is required.
• Flexibility and strike plates protect the CSST allowing it to be run in concealed spaces.
