Certification standards

ISO international standards are globally applicable and authoritative, formulated by the International Organization for Standardization through international consultations. SAE international standards, developed by the Society of Automotive Engineers, focus on technical standards in automotive engineering and guide automotive parts manufacturers in standard quality control. Chinese car industry-developed standards, such as JB/T6303, JB/T5363, and JB/T6442, are often better suited to the sector's diverse requirements.
Introduce
A seal found inside the automatic transmission oil pump is called the automatic transmission oil pump seal. The primary duty of the oil pump, which is an essential part of the automatic transmission, is to transfer hydraulic oil from the oil tank to different areas of the gearbox to maintain the transmission's regular operation. The seal has a sealing function that keeps hydraulic oil from leaking and harming the gearbox's lifespan and performance. This seal is crucial to maintaining the gearbox's regular operation. To guarantee the vehicle's regular usage and driving safety, adequate attention must be given to maintenance and upkeep.

Advantage
The automatic transmission oil pump seal is a crucial rubber component that prevents oil leakage and maintains internal pressure and oil flow rate. Its advantages include an efficient sealing effect, maintaining steady oil flow, and improving the overall efficiency of the transmission system. The seal's precise structural design prevents oil leakage from outside the pump, ensuring stability in pressure and flow. It also allows the oil pump to provide the necessary amount of oil inside the gearbox, allowing it to cool, lubricate, and shield the stationary rotor. High-quality oil pump seals also increase the transmission's safety and durability, making them a positive asset.
