Key Features
- Genuine OEM Steel Construction — Fabricated from hydraulic-grade steel tubing that meets the original pressure and flow tolerances required by the hydraulic circuit on these machines.
- Direct Valve-to-Tank Routing — Pre-formed to the correct routing geometry for a straight-swap installation between the control valve and the hydraulic reservoir — no bending or field modification needed.
- Broad Cross-Model Compatibility — A single part number covers the ST-45HRM, ST-70, and WRS5200, simplifying parts inventory for mixed Multiquip fleets.
- Hydraulic Integrity Preserved — A sound return line keeps fluid cycling cleanly back to the tank, maintaining correct system pressure and preventing heat build-up that can degrade seals and valves throughout the circuit.
- Leak-Free Hydraulic Circuit — Replacing a cracked, corroded, or damaged tube eliminates return-line leaks that can cause unsafe hydraulic pressure loss and fluid contamination on active worksites.
The hydraulic steel tube valve to tank is the return-line conduit that carries hydraulic fluid from the control valve back to the reservoir after it has completed its work cycle. A properly functioning return line maintains steady, consistent back-pressure across the hydraulic system, which is critical for smooth, predictable machine operation. When this tube corrodes, cracks, or develops a fitting leak, fluid loss and contaminated hydraulic oil can rapidly cause downstream damage to pumps, valves, and cylinders — making timely replacement essential to keeping the hydraulic system operating within its designed parameters.
