803107805 XCMG GR2605 motor grader screw plug

The 803107805 screw plug is a specialized sealing fastener for hydraulic and lubrication systems in engineering machinery. It is used to seal pre-drilled holes, drain holes, or fill holes in pipelines and housings, achieving leak-proof sealing. Suitable for heavy-duty and complex working conditions, it features wear resistance, rust prevention, excellent sealing, and easy installation, making it a fundamental component for equipment sealing and protection.

Core Technical Parameters

1. Model: 803107805, a screw plug specifically designed for engineering machinery, precisely fitting the host pipeline and housing mounting interfaces.

2. Compatible Media: Anti-wear hydraulic oil, lubricating oil, and other commonly used media in engineering machinery, meeting sealing and protection requirements.

3. Material: 45# carbon steel/stainless steel, heat-treated for high strength, deformation resistance, and corrosion resistance.

4. Operating Temperature: -40℃~120℃, suitable for harsh outdoor working environments such as high and low temperatures, dust, and oil contamination.

5. Surface Treatment: Zinc plating and passivation/blackening treatment for rust and corrosion prevention, improving sealing performance and service life.

6. Specifications and Dimensions: Thread specifications and outer diameter are compatible with the main unit’s pre-drilled holes, ensuring precise thread alignment without additional adjustment.

7. Sealing Method: Equipped with a matching sealing gasket, providing excellent sealing performance and preventing media leakage.

8. Fitting Precision: High thread precision ensures a tight fit with the mounting hole threads, eliminating the risk of loosening or leakage.

Core Functions and Roles

As a core component for equipment sealing and protection, it is used to seal pre-drilled holes, drain holes, and fill holes in pipelines and housings, achieving media sealing, preventing hydraulic oil and lubricating oil leakage, and ensuring stable system pressure. The high-strength material can withstand internal system pressure and outdoor impacts, preventing deformation and damage. The precise thread design combined with the sealing structure enhances sealing reliability, preventing dust and impurities from entering the system and protecting core components of the hydraulic and lubrication systems. Easy installation allows for quick disassembly and installation, facilitating routine equipment maintenance and oil changes, and extending equipment lifespan.

Suitable Applications

Widely used in the hydraulic and lubrication systems of various construction machinery such as excavators, loaders, bulldozers, and road rollers. Used to seal pre-drilled holes, drain holes, and fill holes in components such as pipelines, gearboxes, drive axles, and hydraulic tanks. Suitable for heavy-duty and complex working conditions such as infrastructure construction, mining, earthwork engineering, and road construction, it is an indispensable basic fastener for equipment sealing and protection.
