Multiquip 509588 Poly Flex Tube 1/2 In. Black

The Multiquip 509588 Poly Flex Tube 1/2 In. Black is a genuine OEM replacement designed for the LS-series hydraulic-driven concrete pumps, including the LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD. As a factory-sourced component, it is manufactured to the exact material grade, diameter, and flexibility specification required for proper hydraulic or fluid routing on these machines. Ordering by part number 509588 ensures you receive the correct tube configuration without guesswork or fitment risk. DHS Equipment stocks Multiquip OEM parts to keep your concrete pump running at full capacity.

Key Features

• OEM-Grade Polymer Construction — Manufactured from the same black poly material specified by Multiquip, maintaining the correct flexibility and pressure tolerance for fluid line applications on LS-series concrete pumps.
• Correct 1/2 In. Diameter — Sized at exactly 1/2 inch to seat and seal properly within the existing fittings and routing of the LS-series pump system, allowing straightforward installation without reworking connections.
• Broad LS-Series Compatibility — Confirmed fitment across LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD hydraulic-driven concrete pump models.
• Maintains Fluid Routing Integrity — A sound, crack-free flex tube keeps hydraulic or control fluids directed precisely where needed; a degraded tube can cause pressure loss, leaks, or inconsistent pump output.
• Direct Genuine OEM Source — Sourced directly through Multiquip's OEM supply chain and sold by DHS Equipment, so part number 509588 matches your machine's original bill of materials exactly.

A poly flex tube serves as a flexible conduit for routing hydraulic fluid, water, or control-line fluid between components on a concrete pump. Its flexibility allows it to bridge moving or offset connection points without cracking under vibration or repeated movement. When a flex tube ages, it can become brittle, develop surface cracks, or collapse internally — any of which restricts flow, causes leaks, or disrupts the hydraulic circuit that controls pump output and consistency. Replacing a worn tube with the correct OEM part restores full flow capacity and prevents unplanned fluid loss during pour operations.
