Oil Pressure Gauge 1/8 0-300 Psi

1/8 BSP Fitting Filled with Glycerine

This 0–300 PSI (0–20 Bar) Glycerine-Filled Oil Pressure Gauge is a high-accuracy measuring instrument suitable for oil, water and air systems. The glycerine filling stabilises the needle during operation, reducing vibration and allowing for clear, reliable pressure readings—ideal for burner commissioning, pump testing and general hydraulic or pneumatic applications.

Featuring a metal case, 63mm dial, and a 1/8" BSP bottom-entry connection, this gauge is a durable, trade-grade tool widely used in oil-fired heating systems, mechanical testing setups and industrial pressure monitoring.
