31QD-10640-5W High Pressure Hose transfers pressurized hydraulic oil for B2B excavator parts repair, replacement inventory, and wholesale sourcing.
The 31QD-10640-5W High Pressure Hose YNF19049 is a hydraulic hose assembly used to transfer pressurized hydraulic oil between corresponding components in a compatible excavator hydraulic circuit. Flexible hose construction allows hydraulic connections to be maintained where vibration, machine movement, or installation geometry makes rigid piping unsuitable.
High-pressure hoses are continuously exposed to hydraulic pressure, oil, vibration, bending, and working-environment conditions. Surface cracking, abrasion, leakage around crimped fittings, hose deformation, or damage to the end connections can indicate that replacement is required.
For B2B buyers, the 31QD-10640-5W hydraulic hose should be verified by part number, overall length, hose diameter, both end-fitting types, fitting angles, thread or port specifications, crimp configuration, and existing-part photos. Pressure rating should not be assumed without confirmed product specifications. Accurate fitment checking helps wholesalers reduce incorrect inventory, installation delays, oil leakage claims, and repeat international freight.

Q: What fluid is transferred through this hose?
A: It is intended for compatible hydraulic oil circuits.
Q: Is a machine model confirmed?
A: No specific machine model has been supplied, so fitment should be confirmed before ordering.
Q: Is the pressure rating confirmed?
A: No. The working pressure specification should be confirmed from the actual product configuration.
YNF Machinery supplies 31QD-10640-5W high pressure hoses and related excavator hydraulic components for repair workshops, fleet operators, machinery dealers, wholesalers, and international importers.
The YNF19049 hydraulic hose assembly is a fitment-sensitive pressure-line component. For professional buyers, part number confirmation should be combined with hose length, diameter, end-fitting style, thread or port dimensions, fitting angles, and crimp configuration before quantity purchasing.
Buyers can provide the 31QD-10640-5W reference number, machine model, required quantity, hose measurements, fitting photos, thread details, installation-location photos, and clear images of the removed hose for confirmation.
Hydraulic hoses, adapters, pipe fittings, seal kits, hydraulic pumps, control valves, cylinders, and other excavator hydraulic repair parts can also be consolidated into the same inquiry to simplify sourcing and reduce fragmented international shipping costs.
