5. FAQ
Q: Can these O-rings adapt to hydraulic oil working environments?
A: Yes, the raw material features excellent resistance to common mineral hydraulic oil.
Q: What temperature range can these O-rings work steadily within?
A: They can keep good elasticity under normal low and medium temperature working conditions.
Q: Are these O-rings prone to swelling when contacting lubricating oil?
A: Formulated rubber material effectively reduces expansion caused by long-time oil contact.
Q: Are all sizes strictly produced according to standard metric dimensions?
A: Every O-ring is manufactured with precise tolerance to match standard installation grooves.
Q: Can these seals be used on both hydraulic and fuel related assemblies?
A: They are mainly suitable for hydraulic circuits; we can suggest other materials for fuel pipelines.
Q: What core construction and mining projects rely on this O-ring kit for regular hydraulic system overhaul?
A: It is designed for routine maintenance of main pump rotary parts on large wheel loaders, widely applied in open-pit mineral mining, aggregate stockyard handling, port cargo stacking and large infrastructure earthmoving projects.
Q: How does the service cycle of graphite modified FKM O-rings compare with ordinary unmodified rubber sealing rings?
A: The graphite doping formula greatly improves high temperature resistance, anti-aging and anti-extrusion performance. Under daily full-load heavy loading conditions, its service cycle reaches 2.6 times that of standard pure rubber O-rings.
Q: Can this set of sealing rings block mine mud, rock dust and suspended hot hydraulic oil mist in harsh long-term outdoor mining working conditions?
A: The dense smooth fluororubber surface isolates tiny sediment and hot oil mist from penetrating pump assembly gaps, and wear-resistant PTFE back rings avoid friction damage mixed with hard mineral dust inside pump cavities.
Q: What practical labor-saving advantages can field maintenance technicians gain from using this fully pre-matched all-in-one O-ring kit?
A: All commonly used specifications required for main pump overhaul are pre-assembled in one set without separate ordering. Maintenance staff do not need to carry scattered loose seals or repeatedly measure dimensions on site, significantly shortening pump repair duration.
