Key Advantages

1. OEM Standard Full-model Compatibility : Strictly manufactured in accordance with Caterpillar’s original technical drawings, dimensional parameters and pipeline connection design requirements, the thread specification, outer diameter, sealing structure and installation size of the fitting are 100% matched with the pipeline systems of Caterpillar 120/135/140/160 motor graders. No secondary processing, tapping or modification is required for installation, ensuring seamless fit with original machine pipelines and components, and consistent connection and sealing performance.

2. High-strength Pressure-resistant Material : Adopts industrial-grade high-strength alloy steel/carbon steel as the main raw material, with surface anti-rust, anti-corrosion and wear-resistant electroplating treatment (zinc/nickel plating), having excellent compressive strength, anti-extrusion and anti-burst performance. It can withstand the high working pressure of the grader’s hydraulic system for a long time, and is not easy to deform or fracture under heavy-load and high-vibration conditions.

3. Precision Sealing Structure Design : Adopts Caterpillar original standard integrated sealing structure (thread seal + cone face seal), with high-precision thread machining and smooth sealing contact surface, ensuring tight fit between the fitting and pipeline/ components, effectively eliminating the risk of medium leakage at the connection, and maintaining the long-term sealing performance of the pipeline system.

4. Anti-vibration & Anti-loosening Performance : The optimized structural design and precise thread fit enhance the anti-loosening performance of the connection, effectively resisting the continuous mechanical vibration of the grader during operation, avoiding the loosening of the fitting and pipeline connection caused by long-term vibration, and reducing the frequency of on-site maintenance and re-tightening.

5. Universal Design Reduces Inventory Cost : As a universal fluid connection fitting for four Caterpillar motor grader models, it realizes the unified configuration of spare parts, eliminates the trouble of purchasing and storing separate fittings for different models, significantly reduces the inventory pressure and spare part management cost of maintenance and operation enterprises.

6. Simple Installation & High Maintenance Efficiency : Conforms to Caterpillar’s original pipeline assembly design, with a compact and integrated structure, and can be quickly installed, connected and replaced with conventional hydraulic tools (wrenches, pipe tongs) without professional technical support. The quick connection feature greatly shortens the on-site maintenance time of the pipeline system and improves the overall maintenance efficiency of the grader.
