SERIES A-169/A-170
INSTRUMENTATION SIPHONS
Protect Instrumentation in High Temperature Applications
ACCESSORIES
The Series A-169/A-170 Instrumentation Siphons protect pressure instruments
in high temperature applications. Water held in the 180° coil prevents steam from
contacting the instrument. Constructed in either carbon steel or 316 stainless steel,
the instrumentation siphons can withstand high temperature, pressure, or resistance
to corrosion. They are ideal for use with pressure gages and instrumentation where
the process media temperature exceeds the rating of the instrument. The male NPT
connection allows for easy installation and secure attachment.
BENEFITS/FEATURES
• Carbon steel construction
• MNPT connection allowing for easy installation
• Stainless steel construction
APPLICATIONS
• HVAC
• Industrial process
