A820205002483 PT1/4-M14 Transition Connector Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The A820205002483 PT1/4-M14 transition joint is a custom-made pipeline adapter for engineering machinery. Its core function is to precisely connect PT1/4 and M14 pipelines, facilitate media transfer, and ensure leak-proof sealing. It features precise connection, tight sealing, and pressure and durability, making it suitable for harsh environments such as mines and construction sites. It effectively connects pipelines of different specifications, prevents oil and gas leaks, and ensures smooth media transfer in hydraulic and pneumatic systems.
As the core “transfer sealing unit” of the engineering machinery pipeline system, this product is designed with precise specifications to perfectly adapt to both PT1/4 and M14 interfaces. It has the functions of conversion, sealing, and force transmission. The threads fit precisely, the sealing performance is stable, it is corrosion-resistant and wear-resistant, and it is easy to install and maintain, extending the service life of the pipeline system. It meets the industry pipeline joint standards and is a high-quality original part for maintenance, replacement, and bulk stocking.
