Key Features
- Genuine OEM Construction — Built to the same material and dimensional standards as the original hose, ensuring correct flow capacity and pressure handling for concrete pump service.
- Exact-Match Replacement — Engineered specifically for the ST45, this hose connects at the same routing points and uses the same end configurations as the part it replaces.
- Confirmed ST45 Fitment — Designed exclusively for the Multiquip ST45 swing tube concrete pump, keeping your parts search straightforward and accurate.
- Maintains Fluid Integrity — A correctly seated hose prevents leaks, maintains system pressure, and keeps the pump delivering consistent concrete output on every pour.
- Direct Multiquip Sourcing — this part is an authorized Multiquip OEM part, giving you confidence that the replacement matches the original in both form and function.
A hose in a concrete pump carries fluid — whether hydraulic fluid, water, or slurry — through critical circuits within the machine. When a hose degrades, cracks, or develops a leak, it disrupts system pressure and can cause poor pump performance or unplanned shutdowns mid-pour. Replacing a worn hose promptly with the correct OEM part keeps the ST45 operating at the pressure and flow levels it was designed to deliver.
