Main Features
This 07260-04720 Hydraulic Oil Suction Pipe is a special-purpose hose for negative-pressure oil suction. It resists collapsing under suction pressure to ensure a stable oil supply to the hydraulic pump.
It offers excellent resistance to hydraulic oil corrosion, high and low temperatures, and aging. It adopts a fiber-reinforced layer with no steel wire required, making it well-suited for low-pressure oil suction working conditions.
As an OEM-interchangeable component, its dimensions fully match OEM specifications for direct drop-in replacement and installation.
It is wear-resistant and performs reliably under harsh construction site conditions and mechanical vibration.
Applicable Scenarios
Suction circuit between hydraulic tank and main hydraulic pump on excavators and bulldozers.
Replacement of hydraulic suction hoses for heavy‑duty equipment operating in mining and construction‑site environments.
Equipment maintenance & part replacement: resolves common failures including hose aging, cracking, collapse and oil leakage.
Construction machinery overhaul and spare‑parts stocking for wearing components.
FAQ
Q1: Which machines does this hose fit?
A1: It fits Komatsu excavators and bulldozers. It is mainly used for the suction circuit between the hydraulic oil tank and main pump. Please cross‑reference your original part number before purchasing.
Q2: What material is this suction hose made of?
A2: Constructed from oil‑resistant synthetic rubber with a fiber‑reinforced layer. There is no inner steel wire; it is specially designed for negative‑pressure suction conditions and features anti‑collapse performance.
Q3: What failure issues can this hose resolve?
A3: It replaces aged, cracked, collapsed or leaking suction hoses. It stabilizes oil supply to the hydraulic pump and prevents pump damage resulting from insufficient oil intake.
Q4: Is this a pressure hose or suction hose?
A4: This is a suction hose, designed for the low‑pressure, negative‑pressure suction side. It is not suitable for high‑pressure oil delivery circuits.
