Hydraulic Accessories:

Donaldson offer an extensive range of hydraulic accessories for hydraulic lines and reservoirs! Finish off your hydraulic circuit with hydraulic filter service indicators, hydraulic pressure gauges, test points assemblies, hydraulic valves, hydraulic flanges, reservoir level gauges, sight glasses, a variety of tank and filler breathers, caps, vents, plugs, strainers, diffusers, magnets and more.

Hydraulic Filter Service Indicators: Service indicators — electrical, visual, pressure, or differential – tell you when to change the hydraulic filter. Mount on the filter head or connect remotely to your central control panel.

Hydraulic Pressure Gauges: Mechanical bourdon tube pressure gauges with glycerine-filled stainless steel bezels and cases in a variety of face diameters are easy to install for continual monitoring of system pressure.

Test Points: Test points can be used as a connection into the hydraulic system on the suction side, pressure side or return. They allow connection for pressure and temperature transducers and provide ports for fluid sampling so you can monitor system cleanliness. Assemblies, adapters and hoses allow access to hard-to-reach lines.

Hydraulic Valves: In-line check valves to 200 gpm flow, ball valves for low, medium and high pressure (up to 7250 psi), two-way and three-way, standard and T-handle styles, also split flange ball valves.

Port Flanges: For connecting components on a hydraulic line we offer split flanges, gage port spacers, elbow flanges, blanking flanges, 4-bolt NPTF and SAE threaded flanges, flat socket weld and butt weld flanges in a broad range of sizes. O-Ring and flat face models, Schedule 61 and 62 options.

Strainers & Diffusers: Strainers remove larger particulate from the fluid in your reservoir or sump. Diffusers reduce aeration, foaming, turbulence and noise caused by return lines.

Breathers: Available in a wide range of styles, materials and sizes. Breathers provide clean airflow into reservoirs and other storage devices where there is an exchange of air during changing fluid levels. Breather caps with pressure relief and vacuum breakers limit air exchange and provide a positive suction at the pump inlet. Styles include spin-on, filler breathers, bayonet style with dip stick options, pressure filler breather caps and more. Prevent airborne contaminant from entering the tank!

Sight Glasses: Leak-free sight glasses come in plastic or metal for use with a variety of fluids. Steel models work well in high pressure and high temperature applications. In areas of low light, prism lens sight glasses provide quick, accurate readings.

Fluid Level Gauges: Gauges that show the oil level, or the oil level AND oil temperature. Steel and polyamide options. Models suitable for pressurized reservoirs.

Reservoir Magnets: Trap and hold ferrous metal contaminants, typically located in the tank. If not contained, these contaminants will cause collateral damage to significant components!

Caps, Plugs & Vents: Donaldson’s range of plastic plugs, caps and vents are a rare find! They’re great for small power units and gearboxes.

Suction & Return Flanges, Weld Risers: These flanges are designed for tank top mounting and provide a seal to the pipe and reservoir without welding.

Replacement Hydraulic Filters: Donaldson offers a broad selection of hydraulic replacement cartridges and spin-ons. Choose from many different filter media to find exactly the right filter to help you meet the cleanliness requirements for your hydraulic system.
