The WIKA mini-siphon is designed specifically to replace the old pigtail and coil siphon. The mini-siphon has a thermal barrier which protects the pressure gauge from harmful steam, hot vapors and liquids, and contains a unique inner chamber that reduces pressure surges and "water hammer". The mini-siphon also eliminates gauge whip and vibration that is typically found on traditional siphons by mounting the gauge closer to the process. When the mini-siphon is first installed, it is recommended to be filled with water or any other suitable separating liquid
