4. FAQ

Q: What construction machine does part number 8T-8381 O ring suit for?
A: Part number 8T-8381 O ring is designed for excavator hydraulic circuit connection sealing and hydraulic oil leakage prevention.

Q: What material is the 8T-8381 O ring made of?
A: 8T-8381 O ring is made of high quality NBR rubber, which has good oil resistance and stable elasticity under normal hydraulic working temperature.

Q: What is the main function of this O-Ring?
A: It forms static sealing at pipe joints and component interfaces, stops hydraulic oil leaking out and prevents air from entering the hydraulic system.

Q: Where will this O ring be installed on the excavator?
A: It fits into the groove of hydraulic connectors, valve blocks and hydraulic component joint faces of excavator hydraulic system.

Q: What working pressure can this O ring withstand?
A: It can adapt to the medium pressure of excavator hydraulic system and keep sealing performance under continuous working vibration.

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.
