Multiquip 30519ZM3000 Tube A, Corrugated (7x18)

The Multiquip 30519ZM3000 Tube A, Corrugated (7x18) is a genuine OEM component designed for DS-Series screed equipment. Sourced directly from Multiquip, this part is manufactured to the exact specifications of the original, ensuring a correct fit within the screed assembly. It is compatible with DS-Series screeds and is the correct OEM replacement when the original tube shows wear, cracking, or loss of flexibility. DHS Equipment stocks this part to help keep your screed running at full capability.

Key Features

• Genuine OEM Construction — Manufactured by Multiquip to match the original corrugated tube's wall thickness, diameter, and flexibility characteristics for consistent performance in the screed assembly.
• Exact-Fit Replacement — Dimensioned at 7x18 to drop into the original mounting position without modification, preserving the integrity of the surrounding components.
• DS-Series Screed Compatibility — Confirmed fitment for DS-Series screed equipment, so you can order with confidence knowing this is the correct part for your machine.
• Maintains Fluid and Air Routing Integrity — A damaged or collapsed corrugated tube disrupts the flow path it serves; replacing it promptly restores proper routing and protects connected components from strain or starvation.
• Durable Corrugated Profile — The corrugated design provides flexibility under vibration and movement while resisting kinking, helping the tube hold its shape throughout the screed's operating cycle.

A corrugated tube in a screed assembly serves as a flexible conduit, routing fluid, air, or fuel between components while absorbing the vibration and positional movement that rigid lines cannot accommodate. The corrugated profile allows the tube to flex repeatedly without cracking or kinking, which is critical in a machine that operates under constant vibration. When this tube degrades — through hardening, cracking, or collapse — it can restrict or interrupt the flow path it manages, leading to poor screed performance or damage to upstream and downstream components.
