Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original hydraulic system specifications, ensuring proper sealing pressure and material compatibility with the hydraulic reservoir or port it caps.
- Direct-Fit Replacement — Engineered to thread or seat exactly as the original, with no rework needed to install on compatible AR13 series rollers.
- AR13 Series Compatibility — Confirmed fitment for AR13D, AR13H, AR13HA/HAR, and AR13HC ride-on asphalt roller models.
- Hydraulic System Integrity — A properly seated hydraulic cap maintains correct system pressure and prevents contamination entry, both of which are critical to consistent roller drum performance and steering response.
- Contamination Protection — Seals hydraulic ports or reservoirs against dirt, debris, and moisture intrusion — failure of this cap can allow contamination that degrades hydraulic fluid and accelerates component wear throughout the system.
A hydraulic cap serves as a sealing closure for a hydraulic reservoir, fill port, or hydraulic line port on the roller's hydraulic circuit. Its primary role is to maintain a clean, pressurized hydraulic environment by preventing fluid leaks and blocking contaminants from entering the system. When a hydraulic cap is cracked, missing, or improperly seated, hydraulic fluid can escape and foreign matter can enter — leading to pressure loss, erratic drum or steering behavior, and accelerated wear on pumps, motors, and valves throughout the circuit.
