4. FAQ

Q: I am looking for o‑ring spare parts for motor grader hydraulic system, could you confirm the corresponding part number?
A: The exact matching part number is 370‑664, this o‑ring seal kit is specially produced for motor grader hydraulic circuit daily maintenance and component overhaul work.

Q: Which equipment position does part number 370‑664 apply to on motor grader equipment?
A: 370‑664 is used for multiple hydraulic connection joints of motor grader, it fits pipe joints, valve ports and auxiliary sealing positions of steering related hydraulic assemblies.

Q: What raw materials are adopted for each sealing piece inside this o‑ring seal kit?
A: Main raw materials are NBR and PU, NBR offers good oil resistance for hydraulic fluid, PU enhances anti‑extrusion performance under medium working pressure.
 
Q: Are these O‑rings produced complying with standard groove dimensional requirements?
A: Every single piece is precision sized to match standard installation grooves for heavy‑duty bulldozer assemblies.

Q: Will frequent thermal cycles cause permanent compression deformation for this rubber ring?
A: Specially formulated rubber compound lowers compression‑set, retaining good elasticity under repeated temperature changes.

Q: Will repeated pressure cycles cause permanent deformation on this rubber ring?
A: Optimized rubber formula reduces compression‑set, retaining elasticity under cyclic pressure changes.

Q: Is this O‑ring suitable for static connection only or can it be used for dynamic moving positions?
A: It performs best for static sealing joints; frequent high‑speed reciprocating motion will shorten its service life.

Q: What engineering scenarios frequently need this O-ring set for routine replacement?
A: It is widely used for maintenance of hydraulic pipeline connectors on large crawler excavators, including large open-pit mining, port cargo handling, mountain road excavation and urban large infrastructure projects.
