The Multiquip 551440380 is a genuine OEM Nylon Tube 6.3 520L designed for the MRX-440P walk-behind roller. Sourced directly from Multiquip, this tube matches the exact material grade, diameter, and length of the original component installed at the factory. Confirmed fitment for the MRX-440P ensures a straightforward swap with no guesswork on compatibility. DHS Equipment stocks genuine Multiquip parts so you can get your roller back in service without delays.
Key Features
- Genuine OEM Material Integrity — Manufactured to the same nylon grade and wall thickness as the original tube, ensuring correct flow capacity and resistance to the pressures and fluids used in the MRX-440P system.
- Correct Length and Diameter — Cut to the OEM-specified 520L length and 6.3mm dimension, so the tube seats and routes exactly as intended without trimming or adapting.
- Confirmed MRX-440P Fitment — Engineered specifically for the Multiquip MRX-440P walk-behind roller; verify by part number 551440380 before ordering.
- Maintains Fluid or Air Routing Integrity — A correctly seated tube keeps the relevant system operating at the pressures and flow rates the roller depends on; a cracked or kinked tube can cause erratic performance or system failure.
- Direct OEM Replacement — Installs using the original fittings and routing path, restoring the machine to its designed operating condition.
The nylon tube on the MRX-440P serves as a conduit for fluid or air within one of the roller's operating systems — routing media between components at the pressures and flow rates required for correct machine function. Nylon tubing is chosen in these applications for its flexibility, chemical resistance, and durability under repeated pressure cycles. When a tube cracks, kinks, or loses its seal at a fitting, the affected system can lose pressure or flow, leading to inconsistent roller performance or a complete loss of function in that circuit. Replacing a worn or damaged tube promptly with a correctly specified OEM part restores normal operation and prevents secondary damage to connected components.
