Hydraulic fitting adapters are different hydraulic components (pumps, pipelines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, and some auxiliary components, such as level gauges, thermometers, pressure gauges, and so on) connected to form a closed circuit of the hydraulic system is to play a role in connecting an accessory. Hydraulic fittings can withstand the high strength of the pressure, if the hydraulic oil fittings have sand holes, small holes or the pressure is too high to withstand such a large pressure and the impact of the burst is quite large. Hydraulic fitting adapters are widely used in the military, energy, petrochemical, electric power, ships, automobiles, rail transport, construction machinery, mining, metallurgy, steel mills, marine engineering and other industries in the hydraulic piping system.
As one of the leading hose adapter manufacturers, we use certified steel, stainless steel, brass, and other alloys that meet or exceed international standards (e.g., SAE, DIN, JIS). Our materials are rigorously tested for hardness, tensile strength, and corrosion resistance.
All Duoli hydraulic hose adapters are manufactured with CNC machining to exacting tolerances. This ensures a perfect fit, eliminating leakage paths and withstanding extreme pressure spikes and vibration.
We offer the most comprehensive hose adapter types in the industry. From common JIC, NPT, and SAE flanges to BSP male connector(BSPP, BSPT), ORFS, and Metric standards, we have the fitting you need.
Simplify your sourcing and reduce procurement complexity. Whether you need elbows, tees, crosses, reducers, or custom designs, Duoli, among hose adapter manufacturers, is your single, reliable source for all connection points.
We offer a range of surface treatments like zinc-nickel plating, black oxide, and passivation to provide superior corrosion protection, extending the life of your components and your entire system of hose fittings adapters.
