Key Advantages

1. OEM Standard Perfect Compatibility : Strictly manufactured in accordance with Caterpillar’s original technical drawings and thread precision requirements, the thread size and structural design are 100% matched with the threaded ports of Caterpillar 120/140 motor grader’s fluid system components, no secondary processing or tapping is required, and it can be perfectly screwed and fitted with the original machine parts without loose or seepage.

2. High-strength Durable Material : Adopts high-quality industrial-grade carbon steel/alloy steel with surface anti-rust and anti-corrosion treatment, which has excellent high pressure resistance, impact resistance and tensile strength, and can withstand the long-term vibration and pressure impact of the motor grader under harsh construction conditions without deformation, fracture or thread slipping.

3. Precision Thread Machining : Processed by high-precision thread rolling equipment, the thread has clear teeth, uniform pitch and smooth surface, ensuring smooth screwing and tight fit with the matching threaded port, effectively avoiding fluid leakage caused by thread gap or poor fit.

4. Strong Environmental Adaptability : The surface is treated with anti-rust oil and anti-corrosion coating, which has excellent oil resistance, water resistance and high/low temperature resistance, and can adapt to the complex construction environment of high temperature, humidity and dust on the construction site, without rusting or aging for a long time.

5. Simple & Efficient Installation : Adopts standard hexagonal/inner hexagonal structural design (in line with Caterpillar original design), which is suitable for conventional maintenance tools such as wrenches. Maintenance personnel can complete the screwing and replacement quickly without professional special equipment, greatly improving the efficiency of on-site maintenance and replacement.
