Pressure Gauge Swivel Adapter

Standard Specification:

  • Max Working Pressure: 6000 PSI
  • Material: 316 SS / 316L SS / 304 SS
  • Size: ½" NPT / BSPP / BSPT

Pressure Gauge Siphon "Coil" Type Siphon

The siphon is used to protect the pressure gauges from the steam or high temperature fluid. Siphon reduces the temperature of the process fluid by dissipating the heat. It also helps to reduce the line surges fluctuations.

Standard Specification:

  • End Connection: NPT / BSPP / BSPT
  • Material: 316 SS / 316L SS,CS / 304 SS
  • Size: ¼", ⅜", ½"

Pressure Gauge Siphon "U" Type Siphon

The siphon is used to protect the pressure gauges from the steam or high temperature fluid. Siphon reduces the temperature of the process fluid by dissipating the heat. It also helps to reduce the line surges fluctuations.
