Hydraulic Fitting with O-ring Video

This video shows in detail the complete production process of our hydraulic O-ring fittings. From the selection of raw materials to CNC precision machining, each step is strictly controlled in terms of dimensions and tolerances to ensure that each product has excellent sealing performance and stable quality.

We especially emphasize the processing of the O-ring sealing part. During processing, we perform precision turning and inspection of the O-ring groove of the joint to ensure that its depth and width perfectly match the O-ring size. This design significantly improves the sealing reliability of the hydraulic system, avoiding common problems such as oil leakage and pressure loss.

Finally, the video also shows the assembly, quality inspection and packaging of the joints. Each batch of products undergoes rigorous seal testing and dimensional inspection to ensure that they leave the factory as qualified products. Whether it is bulk purchase or customized service, we provide our customers with trustworthy hydraulic connection solutions with high standards and efficiency.
