The Vevor hydraulic pressure test kit is designed for testing low, medium, and high-pressure hydraulic systems across a wide range of machinery. It includes five gauges, twenty couplings, four quick couplers, and three hoses for versatile diagnostics and pressure comparison. Glycerin-filled gauges help improve reading stability by reducing vibration and internal friction, while the 304 stainless steel housings enhance durability. With compatibility across G, M, UNF, and NPT thread types, this kit is suited for excavators, loaders, bulldozers, farm machinery, and maintenance applications.
