AutoMeter's 66.7mm 35 PSI mechanical water pressure gauge uses a precise Bourdon tube movement to monitor cooling system pressure and connects via an 1/8" NPT fitting for straightforward installation. The gauge includes accessory hardware typical of AutoMeter kits and features incandescent perimeter illumination. It provides a larger‑diameter option for clear, mechanical pressure indication in severe‑service environments.
