Temperature Resistance
NBR: Operating temperature -25°C to +110°C; short-term peak +120°C
HNBR: Operating temperature -30°C to +150°C; short-term peak +175°C, suitable for high-temperature engine bay areas
Oil Resistance (IRM 903 engine/gear oil immersion, 100°C, 70 h, ISO 1817 / ASTM D471)
NBR: Volume swelling ≤25%; no hardening, no surface cracking
HNBR: Volume swelling ≤12%; minimal performance degradation under long-term oil mist exposure
Wear and Fatigue Testing
Reciprocating tension-compression fatigue test: 500,000 cycles, simulating real shift actions; no cracks, dimensional change <5%
Dust boot flex fatigue: 300,000 flex cycles, no fracture at bellows folds
Design service life: Meets 250,000 km road use requirement under normal operating conditions
Environmental Resistance
Ozone aging resistance: 50 pphm ozone environment, 72 hours, no surface cracking
Water and dust protection: IP65 achievable with proper assembly, blocking splashed water, road dust and debris ingress

Vehicle Compatibility Confirmation
To confirm whether a part matches, please provide:
1.Vehicle brand + model + production year
2.Transmission type: MT / AT / DCT
3.OEM original part number (if available)
4.Or provide a clear photo of the old part. Our engineering team can match or re-develop the corresponding rubber part.
Applicable vehicles: Sedans, SUVs, MPVs, light pickups / light commercial vehicles. Supports aftermarket replacement and OEM new project customization.
Core Product Advantages
1.Improved shifting feel: Reduces sticking and abnormal noise, ensures crisp and smooth gear changes, improves driving experience
2.Extended drivetrain life: Protects internal cable core and transmission from dust, moisture, oil corrosion and mechanical wear, reducing aftermarket failure rates and maintenance costs
3.Reliable driving safety: Stable sealing and vibration damping maintain shift operation accuracy, preventing loose shifting or shift failure caused by rubber aging or foreign matter ingress
