100mm Brass Stainless Gauge

In stock


The Q4000 Series gauge is very similar to our P4000 gauge, but has brass internals. This gauge has a stainless steel case and can be liquid filled. It is a very popular pressure gauge and is suitable for most conditions and all applications where you need a low cost but long-life 100mm gauge.

The gauge is standard with bar/PSI and ½ NPT thread.

The Q4000 Series is the ideal gauge for pumps, filters, air compressors, boilers, or any industry where you need a bigger gauge that can be adjusted and calibrated if required. They can be supplied with a calibration certificate if required.

We only stock these in bottom entry but can order in rear entry for that special project or equipment.
