This product is specifically engineered to provide superior protection against flash fires and corrosion in natural gas and propane systems.
The XR3TRM-8 fitting is part of the Gastite XR3 series, which is recognized for its advanced features and robust design. This particular model comes with a built-in flash-shield, offering an additional layer of safety against flash fires that can be caused by electrical sparks. The flash-shield is designed to deflect sparks and prevent them from igniting the CSST (Corrosion-Resistant Steel Tube) line.
The XR3TRM-8 is a CSST (Corrosion-Resistant Steel Tube) 1/2 term flang-1/2 NPT (National Pipe Thread) fitting. The CSST technology used in this fitting is resistant to internal corrosion caused by hydrogen sulfide (H2S) and other corrosive gases. This makes it an ideal solution for applications where traditional black steel pipe fittings may not provide adequate protection.
The XR3TRM-8 is manufactured using a seamless, single-piece construction, ensuring a strong and leak-free connection. The flang connection allows for easy installation and removal, while the NPT threading provides a standardized connection method that is widely used in the industry.
This fitting is also equipped with a pressure-relief device (PRD), which is designed to activate in the event of an overpressure situation. This safety feature helps prevent catastrophic failures and potential damage to property and personnel.
In summary, the Gastite XR3TRM-8 Flash-Shield XR3 CSST 1/2 Term Flang-1/2 NPT Fitting is a top-tier gas fitting that offers advanced protection against flash fires, corrosion, and overpressure. Its robust design, ease of installation, and industry-standard connections make it a reliable and practical solution for various natural gas and propane applications.
