VG1246070010 Genuine SINOTRUK O-Ring Seal - FKM Viton Hydraulic Seal for HOWO Steering Cylinders

VG1246070010 O-Ring Seal – SINOTRUK Hydraulic System Guardian‌

‌The Pressure-Proof Barrier‌
This ‌OEM SINOTRUK O-ring‌ (Part# VG1246070010) uses aerospace-grade FKM compound to seal HOWO truck steering cylinders under 35MPa dynamic pressure. Its cross-section tolerance of ±0.08mm ensures zero leakage even after 500,000 steering cycles in mining operations.

‌Material Science Advantages‌

• ‌Compound‌: Viton GLT-S (70±5 Shore A) with 300% elongation
• ‌Temperature Range‌: -25°C to +200°C continuous (SAE J200 Class HK)
• ‌Chemical Resistance‌: ASTM oil #3 swell <10% after 1000h
• ‌Compression Set‌: ≤15% after 168h @ 200°C (ASTM D395 Method B)

‌Technical Specifications‌

‌Quality Certifications‌
✔ 100% dimensional inspection per ISO 3601-1
✔ Lot-traceable material certificates
✔ Passed 500hr hydraulic impulse test (SAE J2643)
✔ Matches OE groove design with 20-25% compression rate

‌Compatibility‌: Also works on SINOTRUK dump truck lift cylinders when used with backup rings.

‌Installation Tip‌: Lubricate with ester-based grease only – petroleum products degrade FKM.
