SS 304 U-Type Syphon Specifications
Metline’s SS 304 U-type gauge syphons, also widely referred to in the Delhi-NCR market as pigtail syphons, gauge syphons or steam gauge syphons, act as a cooling loop between the process line and the pressure gauge, condensing steam or hot vapours before they reach the instrument. Available in both U-type and coil-type looped designs, and compatible with compression tube fittings and SS 304 pipe fittings across a project, these syphons can also be supplied fitted with pressure gauges and, where required, with an in-line gauge isolation valve for maintenance without shutting down the process line.
