Product Advantages

🚗 Universal Adjustable Fit for Most Vehicles

This adapter is designed with a 22mm inner diameter and a maximum 58mm outer diameter. The adjustable claw bracket and rotating knob allow flexible clamping on most mainstream car brake fluid reservoirs, perfectly compatible with Honda, Toyota, Buick, GMC, Mazda and more vehicle brands. Equipped with a 90-degree elbow connector and 360° rotatable joint, you can freely adjust the tube angle to match your operating space restrictions.

🔌 Four Standard Quick Couplers for Global Vehicle Types

Comes complete with 4 different quick plug adapters, covering American standard, Japanese standard, European standard and general metric systems. One kit meets the connection demands of most regional vehicle models, no extra adapters need to be purchased separately to cut your tool cost.

🛡️ Leakproof Wear-Resistant Sealing Structure

The bottom contact part adopts high-quality molded oil-resistant rubber pad. It fits closely with the reservoir mouth to form a fully sealed state during brake fluid extraction and filling. It effectively stops brake fluid spills, avoids engine compartment corrosion caused by leaked liquid, and prevents air from infiltrating the brake system to guarantee accurate brake bleeding results.

💎 Durable Premium Aluminum Alloy Construction

The main body is made of sturdy aluminum alloy with anti-corrosion surface treatment. The metal bracket and threaded structure resist abrasion, brake fluid erosion and long-term frequent use. It maintains stable clamping force without deformation, durable enough for heavy daily use in auto repair shops and long-term personal garage use.
