STOP GUESSING WHEN TO CHANGE YOUR FILTER ELEMENTS
Donaldson pressure gauge with 1/8 inch NPT thread. Shows filter condition at a glance so you know when to swap elements before flow drops off.
See pressure, swap smart
Most blokes change filters on a calendar schedule or when the pump starts wheezing. This gauge tells you exactly when the element is clogged. Thread it into your Donaldson housing, watch the needle, and swap the element when it hits red. No wasted consumables, no surprise flow drops in the middle of a job.
Standard NPT thread, light body
1/8 inch NPT is the common port on most diesel and hydraulic filter housings. The gauge weighs 0.1 kg, so it does not load the housing or require extra support. Screw it in, tighten by hand plus a quarter turn with a spanner, and you are done.

Frequently Asked Questions
Can't find your answer?
Contact UsWhat is the Donaldson pressure gauge?
A screw-in dial gauge that shows differential pressure across a filter element. When pressure climbs into the red zone, the filter is clogged and needs replacing.
What thread does it use?
1/8 inch NPT. This is a common thread on Donaldson and many other filter housings. Check your housing port before ordering.
Do I need to calibrate it?
No. The gauge is factory-calibrated. Just thread it in and read the dial. Zero the needle if your housing is empty before you pressurise the system.
What if my housing port is BSP, not NPT?
You will need an NPT to BSP adapter bushing. Contact sales@goind.com.au or 07 3204 2240 if you need help sourcing the right fitting.
What warranty and support do I get?
12 months on manufacturing defects. Gauge damage from over-pressure or rough handling is not covered. For technical questions or bulk orders, call 07 3204 2240 or email sales@goind.com.au.
