Series A-169 Carbon Steel Siphon

Brand: Dwyer Instruments, LLC

The Series A-169 Carbon Steel Siphons protect pressure instruments in high temperature applications.

Water held in the 180° coil prevents steam from contacting the instrument. Constructed with carbon steel, the A-169 siphons can withstand high temperature and pressure. 

They are ideal for use with pressure gauges and instrumentation where the process media temperature exceeds the rating of the instrument. The male NPT connection allows for easy installation and secure attachment.
