Profec 63 mm Dry Pressure Gauge — 0 to 25 bar, Back Connection 1/4″ BSP Male
This dry-type pressure gauge from Profec provides reliable, at-a-glance pressure readings across a 0–25 bar (0–350 psi) dual-scale dial. The 63 mm case diameter gives a clear, easy-to-read display, while the back-entry 1/4″ male thread allows flush panel or inline manifold mounting without side protrusion. The dry (glycerine-free) design keeps the unit lightweight and suited to stable, low-vibration installations such as pool filtration lines, irrigation headers, and booster pump outlets.
The Bourdon tube measuring element is manufactured from phosphorous bronze on units rated above 60 bar; on this 0–25 bar version the wetted internals use copper alloy, providing good corrosion resistance against potable water, pool water, and common irrigation media. The black steel case with polycarbonate window protects the movement against dust and accidental contact. Accuracy class 1.6 % of full scale meets EN 837-1 requirements for general industrial and water-treatment applications.

Compatibility
The 1/4″ BSP male back-connection thread mates directly with 1/4″ female BSP ports found on pool filter housings, irrigation manifolds, pressure-reducing valves, and pump outlet flanges. Suitable for use with water, air, and non-aggressive fluids compatible with copper alloy wetted parts. Not recommended for highly corrosive media or high-vibration installations where a glycerine-filled gauge would be preferable.

In details
- Compact 63 mm dial with dual bar/psi scale for quick field readings
- Back-connection entry keeps plumbing tidy on panel or manifold mounts
- Standard 1/4" BSP male thread fits the vast majority of pool and irrigation fittings
- Accuracy class 1.6 % provides reliable measurement for filtration and pump monitoring
- Dry design — no glycerine leakage risk when window seal ages
- Dry type is unsuitable for high-vibration or pulsating pump installations — a glycerine-filled model is recommended in those cases
- Copper alloy internals limit compatibility to non-corrosive, non-ammonia-based media
- No back-entry swivel; connection orientation is fixed at installation
