Interstate Pneumatics G7122-160 Oil Filled Pressure Gauge for Compressors & Regulators

The Interstate Pneumatics G7122-160 is an oil-filled pressure gauge designed for hydraulic or pneumatic systems where vibration and pulsation are common. Oil-filled models like this one use a damping liquid inside the case to cushion internal components, delivering steadier readings and longer life in harsh environments. Key features typically include a Bourdon-tube sensing element, a rugged stainless or brass case, and oil-fill that reduces needle flutter under vibration. Compatible models and connection types depend on the G7122-160’s specific port size and thread standard; common configurations include standard NPT or BSPP male/female fittings and regional pressure ranges. Durability notes emphasize resistance to shock and pulsations, while safety and usability considerations highlight proper calibration, regular inspection for oil leakage, and keeping the gauge within its rated temperature and pressure limits.
