Gastite XR3 Male Adapter – 1" CSST x 1" M-NPT (MFG# XR3FTG-16)The Gastite XR3 Adapter provides a secure, lightning-resistant connection between 1" FlashShield / FlashShield+ CSST tubing and 1" male NPT threaded gas piping. This precision-machined brass fitting uses the patented XR3 multi-layer system designed to enhance safety, improve electrical dissipation, and maintain long-term leak-free operation.
FlashShield+ CSST incorporates a unique metal mesh and twin semi-conductive jackets to dissipate lightning energy—this XR3 adapter is specifically engineered to maintain that protection. No additional bonding or spacing requirements are needed, making installation faster and more straightforward than older conductive CSST systems.
This fitting is field-proven, contractor trusted, and designed to meet the strict requirements of ANSI LC1024 and LC1027 for protective jacketed CSST.Key Features1" CSST to 1" Male NPT adapterPremium machined brass XR3 connection fitting
