The Multiquip 518821 Fitting Straight 8-8 F42EDMX-S is a genuine OEM hydraulic fitting designed for the AR14H asphalt ride-on roller and WTB-16 and WTB-16PD power buggies. As a direct Multiquip OEM component, 518821 is produced to the same specifications as the original part, ensuring a consistent, leak-free connection in your machine's hydraulic circuit. DHS Equipment stocks this part to keep your roller or buggy operating without unnecessary delays. Confirm your model against the fitment list before ordering to ensure accurate parts selection.
Key Features
- OEM Hydraulic Integrity — Manufactured to Multiquip's exact thread form and port geometry, maintaining rated pressure capacity without sealing compromise.
- Straight 8-8 Configuration — Male-to-female straight-through design allows direct in-line installation into existing hydraulic plumbing with no adapters needed.
- Broad Model Coverage — Fits AR14H ride-on asphalt rollers and WTB-16 and WTB-16PD track power buggies under a single part number.
- Leak Prevention at the Source — A correctly seated hydraulic fitting sustains system pressure; a cracked or cross-threaded fitting causes pressure drop, fluid loss, and potential hydraulic failure.
- Genuine OEM Part Number — Part number 518821 is sourced directly from Multiquip, so you receive the identical component originally installed at the factory.
A straight hydraulic fitting serves as the fixed connection point between two hydraulic lines or between a line and a component port, maintaining a sealed, pressurized fluid path within the system. When a fitting fails — through thread damage, cracking, or seal degradation — hydraulic fluid escapes, pressure drops, and the affected system loses the force needed to drive functions such as travel, braking, or blade control. Replacing a damaged fitting promptly with the correct OEM part restores full system integrity and prevents downstream damage to pumps, cylinders, and hoses.
