Racor RK 19668 RK19668 Vacuum Gauge Kit - Includes Fittings

Racor is pleased to announce the following improvements to the Fuel Pressure and Restriction Gauge Improvements include: Stainless Steel case and face increased from 2.0 inches to 2.5 inches diameter for easier reading. The improved cases feature a pressure relief valve to adjust to ambient barometric pressure changes. Gauges with acrylic lenses upgraded to polycarbonate. Needle stops replaced with internal locking Mechanism to prevent damage due to an accidental overpressure. Internal sealing at the fitting, lens, and pressure relief valve reduces the likelihood of internal contamination by splashing fluids.
