Profec Pressure Gauge Glycerin-Filled Bottom 1/4" BSP 0–10 bar

Profec Glycerin-Filled Pressure Gauge — Bottom Connection, 1/4″ Male BSP, 0–10 bar

This Profec glycerin-filled pressure gauge provides stable, easy-to-read pressure monitoring for pool filtration systems, irrigation networks, and greenhouse drip or sprinkler lines. The glycerine fill dampens needle vibration caused by pump pulsation or water hammer, extending gauge life and improving reading accuracy under dynamic flow conditions. The brass male 1/4″ BSP bottom connection threads directly into standard gauge ports on filters, pressure regulators, and manifolds.

The dial face features a clear 0–10 bar scale with a green safe-zone arc (approximately 1–3 bar) and a dual-needle indicator, allowing operators to set and verify target operating pressure at a glance. The black steel case with a flush bezel protects the internal Bourdon tube mechanism from knocks and UV exposure, making it suitable for outdoor and greenhouse installations. Two front-face screws allow the dial to be recalibrated or serviced without removing the gauge from the line.
