1198 Finned Siphon

Brand: Ashcroft Inc
Does not ship to United States

The Ashcroft® 1198 Finned Siphon protects pressure instruments from the effects of elevated temperatures. 

A reduced orifice decreases the volume of the process in the siphon allowing efficient heat transfer between the process and the siphon. 

The siphon's metallic fins maximize exposure to the ambient temperature for effective dissipation.
