The Renator 1/4″ NPT stainless steel water pressure gauge is built to last. The gauge is made from rust-free stainless steel, and is filled with glycerin oil to protect the internal components of the gauge from friction and bumps to increase longevity.

This calibrated bourdon pressure gauge relies on a flattened tube that straightens when pressurized, which converts into the rotation of a gear. This technology is used for high accuracy. The large dial makes for clear and easy reading of pressure.
