What to know before buying

Listing details to confirm

The title claims a red pointer and 3-2-3% accuracy, while the feature text calls the gauge a reset-pointer model without explaining the accuracy notation. The listing identifies the casing as iron, while the description separately claims an iron shell. Confirm the pointer details, accuracy meaning and actual materials against the selected listing. BSP sizes are nominal and do not represent actual diameter.

Who is it for?

A good fit for

Buyers seeking a mechanical pressure gauge for a compatible well-pump or water-pressure setup with a stated 0–20 bar / 0–300 psi scale.
Installations where centre-back mounting, a 2-inch dial and BSP fittings are suitable.
