Multiquip EM509588 Poly Flex Tube 1/2 In. Black

The Multiquip EM509588 Poly Flex Tube 1/2 In. Black is a genuine OEM hydraulic line component designed for LS series hydraulic-driven concrete pumps, including the LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD. As a direct OEM replacement, EM509588 is manufactured to the exact material grade and dimensional spec of the original, ensuring a proper seal and correct flow path within the hydraulic or fluid routing system. Sourced directly through Multiquip's authorized parts network, this tube matches the original in wall thickness, flexibility rating, and fitting compatibility — no field modification needed to make it work. DHS Equipment stocks this part to keep your concrete pump running on schedule.

Key Features

• OEM Material Match — Manufactured from the same polyethylene compound as the original, maintaining the correct flexibility and pressure tolerance for hydraulic fluid routing in LS series concrete pumps.
• Correct 1/2 In. Diameter — Sized at exactly 1/2 inch inner diameter to connect directly to existing fittings and ports without adapter hardware or rework.
• Broad LS Series Compatibility — Verified fitment across LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD Mayco hydraulic concrete pumps.
• Maintains Fluid Routing Integrity — A cracked or degraded flex tube causes fluid leaks, pressure loss, and potential pump output failure; replacing with a correct OEM tube restores consistent hydraulic performance.
• Genuine OEM Part — Supplied under Multiquip part number EM509588, sourced through the authorized distribution network for verified authenticity.

A poly flex tube serves as a flexible conduit within the machine's fluid routing system, carrying hydraulic fluid or ancillary fluids between components that require movement tolerance or vibration isolation. Unlike rigid hard lines, a flexible poly tube absorbs machine movement and reduces stress at connection points, preventing premature fitting failure. When this tube cracks, kinks, or deteriorates, fluid pressure drops, leaks develop, and pump output becomes inconsistent — making timely replacement critical to keeping the concrete pump operating at rated capacity.
