Product details

Pressure Gauge Syphons (also known as syphon tubes or condenser loops).They are bent metal tubes designed to protect delicate pressure gauges, transmitters, and switches from high-temperature fluids, steam, or pressure spikes [1].⚙️ Main Styles ShownPigtail / Coil Syphons (Circular Loops): The full-turn circular loop style. These are designed for vertical pipeline installations.U-Type Syphons (U-Bends): The straight 180-degree curved style. These are designed primarily for horizontal pipeline installations.Coiled Tube (Top): A multi-turn coiled design used for extreme heat dissipation.🛠️ How They WorkThermal Barrier: The loop or bend traps condensed liquid from the process fluid (like steam). This trapped liquid acts as a stagnant cooling barrier, preventing hot live steam from making direct contact with the internal sensing elements of the pressure gauge.Dampening Spikes: The physical shape of the coil helps absorb sudden water hammer pressure spikes or pipeline vibrations that could knock a gauge out of calibration.💡 Common ApplicationsSteam Boiler Lines: Crucial for isolating gauges from superheated steam.High-Temperature Water Systems: Protecting sensors from extreme process heat.Industrial Burners and Heat Exchangers: Installed directly upstream of pressure instrumentation.If you are planning to install these into a line, tell me:What fluid or gas is running through the system?What is the operating temperature and pressure?What end connections do you need to match (e.g., 1/4“ or 1/2” NPT/BSP threads)?I can help you choose between the Pigtail vs. U-type configurations for your installation space!
