ARO 94820 O-Ring
The ARO 94820 is a o-ring intended for maintenance, repair or operation of compatible ARO equipment. The available product data identifies the material as Polyurethane.
For maintenance teams and buyers, the exact manufacturer part number is the most important reference when matching this component to an existing pump or air-system assembly.
Product-Specific Service Role
This component is selected by part number for use in the applicable ARO assembly. Its service role depends on the complete pump or accessory configuration, so technicians should confirm the model plate, parts diagram and current component before installation.
Using the documented part number rather than appearance alone helps reduce ordering errors, especially where similar seals, valves, kits or hardware are used across multiple ARO product families.
Maintenance and Inspection
During service, inspect the surrounding assembly for wear, contamination, damaged sealing surfaces, loose hardware or other conditions that could affect performance. Replacing one component may not correct a broader maintenance issue if adjacent parts are also worn.
If the repair involves a service kit, compare the kit contents with the individual components already planned for replacement to avoid duplicate purchasing.
Compatibility Guidance
Compatibility should be confirmed using the complete ARO model and the applicable parts or service documentation. Similar-looking components can differ by material, size, port configuration, pump series or revision.
Before ordering, verify the part number 94820, the equipment model, the component position in the assembly and the required quantity.
