52mm Oil Pressure Gauge
| Reads | Engine oil pressure |
|---|---|
| Range | 0–5 bar (75 psi) or 0–10 bar (145 psi) |
| Resistance | 10–185 ohms |
| Gauge size | 52mm diameter |
| Power | 12V or 24V |
| Face | black or white |
| Bezel | black or white plastic, or 316 stainless |
Like all products in the Wema range, our analogue instruments are built to last. Designed to be accurate, reliable and dependable over years of use.
Oil pressure is one of the most critical readings on any engine. A drop below safe operating pressure causes damage quickly — and without a reliable gauge you won't know until it's too late. This is an instrument where accuracy and dependability really matter.
Available in two pressure ranges to suit different engine specifications:
- 0-5 bar — suitable for most standard petrol and diesel engines
- 0-10 bar — for higher pressure applications
Works with any 10-185Ω pressure sender — Wema or any other manufacturer's sender with a matching resistance.
IP67 rated — sealed completely against dust and waterproof to 1m depth for 30 minutes, the highest standard for a gauge, giving you confidence to install it on anything from a boat to an excavator.
Fits any standard 52mm panel cutout. Retrofits straight into most existing dashboards without modification.
Runs on 12V. For 24V systems a dropping resistor is supplied — or a voltage regulator for a cleaner, more stable long-term solution.
Red or amber backlight. Available in black or white face with black, white or brushed stainless bezel — the same Wema styling across the full gauge range, so everything matches.
We stand behind our products with a 3-year guarantee.

Fitting on 12V or 24V — and why a voltage regulator helps
A 12V system is never a steady 12V: it sags under load, rises to 14V or more on charge, and spikes as things switch on and off. The gauge sees all of it, so readings can wander with the state of the electrics rather than with what you’re measuring. A voltage regulator delivers a clean, steady voltage whatever the supply is doing — so the gauge reads consistently, the backlight stays even, and sensitive electronics are protected from spikes.
On a 24V system a dropping resistor is supplied to suit the gauge, but a regulator is the better option: resistors run hot, waste power and add a failure point at each gauge, whereas one regulator feeds the whole dashboard from a single clean supply (the 3A model runs up to 20 standard 52mm gauges, the 5A up to 38).
