Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications for consistent flow capacity and flexibility under operating conditions.
- Direct-Fit Replacement — Sized at 5/16" to match the original routing and connection points, allowing straightforward installation on compatible AR-series rollers.
- Confirmed AR-Series Compatibility — Verified fitment for AR13HA/HAR and AR13D asphalt ride-on roller models.
- Maintains Fluid Routing Integrity — A compromised or degraded flex tube can cause leaks or restricted flow; replacing with the correct OEM part restores proper fluid delivery and system performance.
- Flexible Design for Vibration Tolerance — The flexible construction accommodates machine movement and vibration inherent to roller operation, extending service life compared to rigid line alternatives.
A flex tube routes fluid through areas of a machine where rigid lines are impractical — typically bridging moving components or navigating tight routing paths where some degree of flex is needed to prevent cracking or fatigue failure. On AR-series asphalt ride-on rollers, maintaining the integrity of these lines is essential to keeping hydraulic or fluid systems functioning correctly. When a flex tube cracks, kinks, or deteriorates, it can cause fluid loss, pressure drop, or contamination that affects machine operation — making timely replacement with the correct OEM part critical to keeping the roller productive.
