Dwyer A-169 Pressure Carbon Steel Siphons

Dwyer 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 temperatures and pressure. 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.

Pressure Snubbers are used with water, air, gases, and oils. Mounting Kits for Magnehelic gages, Strap Wrenches for uncommonly shaped objects, and Tubing in materials like rubber, aluminum, Norprene and more are available. Static Pressure Tip Sensors are used for different products.
