This looped siphon tube installs between the process pipe and pressure gauge to reduce direct heat exposure and moderate pressure pulsation. Typical installations include steam piping, boilers, hot-liquid equipment and hydraulic pressure monitoring.
The 316 stainless steel tube provides corrosion resistance for compatible process media. Its union connection allows the gauge or tube to be removed for service, while the threaded interfaces provide a compact connection to the pressure system.
