Air Removal for Cooling System Efficiency

Coolant Air Bleeder Screw products remove trapped air from engine and equipment cooling circuits. These screws help maintain smooth coolant circulation for reliable cooling performance. Our products support thread sizes from M2.5 to M20, with overall lengths ranging from 5mm to 50mm. These components help improve cooling system reliability and efficiency in various automotive and industrial applications.

Precision Sealing Surfaces for Leak Prevention

Sealing surface flatness is critical for preventing leakage in bleeder screws. We guarantee sealing surface flatness within ≤0.005mm, with thread accuracy meeting Grade 6g standards. Flat sealing surfaces create tight contact with mounting hole faces. This provides reliable sealing performance and prevents coolant leakage under high-pressure and high-temperature operating conditions.

Complete Machining Capabilities

Our machining capabilities cover production requirements from miniature to medium-size screws. Tsugami S206A Swiss-type lathes perform high-precision machining for small specification screws, while Takamatsu CNC lathes process larger components. Our company has focused on precision machining since 2007. We have implemented digital production management systems to optimize scheduling, production control, and quality management. Every batch undergoes complete dimensional, appearance, and sealing surface inspection before shipment. Our Coolant Air Bleeder Screw products maintain stable quality and consistency across different production volumes.

One-Stop Procurement Support

We provide one-stop procurement support for global customers. During pre-sales, our technical team offers free drawing evaluation and optimization suggestions. During production, we strictly follow approved sample standards. After delivery, dedicated personnel handle quality-related issues and provide professional support. Coolant Air Bleeder Screw products support various trade terms and multiple currency payments. We can also print customer brand logos and specification information on packaging according to specific requirements.
