60075542 plug Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a core sealing component for hydraulic system pipelines and valve groups, the 60075542 plug boasts four major advantages: “tight sealing, high hardness, easy installation, and corrosion resistance.” It is widely used in hydraulic pipelines, valve groups, and valve blocks of construction machinery such as excavators and loaders, serving as a sealing agent for oil circuit interfaces, reserved holes, and inspection holes. Relying on the precise fit between the precision thread and the sealing surface, it achieves leak-free sealing, preventing media leakage, isolating impurities, avoiding pipeline blockage and valve group failure, adapting to high-pressure working conditions, and being easy to install and disassemble, meeting the sealing requirements of complex operating environments.
Compared to ordinary plugs, this product uses high-quality materials and is precision-machined, strictly following the GB/T 24919 standard. The main body is made of 20# forged steel (stainless steel can be customized), with anti-corrosion surface and precision grinding of the sealing surface. It is manufactured through multiple processes, resulting in a dense structure, high thread precision, tight fit, high pressure resistance, wear resistance, and rust resistance. It solves problems such as sealing leakage and thread stripping, reduces maintenance costs, accurately matches the sealing needs of engineering machinery, and has strong versatility.
