Description
• Robust construction resistant to extreme vibration and pulsation
• Universal fill compatibility for flexibility of filling with glycerin or silicone
• All brass internals
• Polished crimp-on bezel
• Engineered restricted orifice available to protect against additional pressure spikes
• Polished crimp-on bezel
• Ventable fill plug for easy venting of case pressure
• Single (psi) or dual scale (psi/kPa)/(psi/bar) available
• Optional U-Clamps, front and back flanges
