150902030076A003 Pressure test plug Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 150902030076A003 pressure test plug is a core sealing component of hydraulic systems. It is primarily used for sealing and locking pressure test holes in oil cylinders and oil circuits, serving both pressure detection and normal oil sealing functions to effectively prevent oil leakage and pressure relief. The product is crafted from high-strength metal with precision machining, undergoing hardening, thread grinding, and anti-corrosion treatment. Its threads are regular, with sufficient hardness, making it pressure-resistant, impact-resistant, and resistant to stripping and deformation. It is suitable for heavy-duty continuous operation conditions such as earthmoving and mining.
This original factory pressure test plug features precise threads and a tight fit, ensuring stable leak prevention and excellent pressure stabilization under high-pressure conditions. During normal operation, it can seal the pressure test hole and lock the oil circuit pressure. During equipment maintenance, it allows for quick disassembly and connection to instruments, balancing sealing performance with maintenance efficiency. Old plugs are prone to thread wear, stripping, loosening, and seal failure, leading to oil circuit pressure leakage, interface oil seepage, and unstable pressure, resulting in insufficient equipment power and frequent malfunctions. This product is an original factory standard part, supporting in-situ non-destructive replacement, suitable for equipment maintenance, overhauls, and bulk stocking, effectively stabilizing hydraulic pressure and reducing operating costs.
