• Glass Cylinder Pressure tested to 1200 psi, To provide a safety factor of 4 at max operating pressure of 300 psi
• Thermal expansion characteristics of piston and cylinder are matched so binding does not occur during temperature variations
• Eliminates 3 way manifold and subtraction method of determining differential pressure
• Design provides automatic dampening against pressure fluctuations so calibration will not be affected
• Easily changed 10 micron filter on high pressure side of gauge protects internal components
• Housing is anodized aluminum
• 0-15 psi or 0-30 psi Differential Pressure indication ranges available
• Extremely Rugged housing protects internal components, acceptable for sustained vehicle usage.
• Optional flush mount unit available for panel installations.

• Ultraviolet shield for av gas use
• 1/4 Three Way spring return valve and vent for 1/4 tubing

Use ultraviolet shield option if gauge is used for Av gas, this provides an ultraviolet shield to prevent accumulation of fuel dye inside cylinder.

Use three way spring return valve option to Conform to API 1581. A three way valve with a vent tube is a provided so that the low pressure connection can be vented to the atmosphere to verify piston movement and position as per API Bulletin 1581 Instructions.
