Pressure Gauge Swivel Adapter
Standard specification :-
Size : ½" NPT / BSPP / BSPT
Material : 316 SS / 316 L SS / 304 SS
Max Working pressure : 6000 PSI
Pressure Gauge 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 :-
Size : ¼", , ½"
End Connections : NPT / BSPP / BSPT
Material : 316 SS, 304 SS, 316 L SS, CS
Thermowells
With the help of variable orifice, these gauge snubbers protect
pressure gauges by reducing fluctuations.

Material :- 316 SS / 304 SS / 316L SS or any special material
