yixunmold
Material: High-performance engineering plastic (PA66/PPO blend) for excellent heat resistance, chemical resistance, and durability.
Structure: Cylindrical main body with two mounting wings for secure installation; top barbed port for quick hose connection; built-in one-way valve mechanism.
Markings: Embossed "ATM" (Air Tight Mechanism) and downward arrow to indicate the approved flow direction (top to bottom), ensuring correct installation.
Surface Finish: Matte black finish for anti-glare and wear resistance, suitable for harsh under-hood environments.
| Advantage | Details |
|---|---|
| Precision One-Way Flow Control | Ensures unidirectional fluid/air flow, preventing backflow and maintaining system pressure stability. |
| Durable Engineering Plastic | Resists high temperatures, automotive fluids (oil, fuel, coolant), and vibration, extending service life. |
| Easy Installation | Integrated mounting tabs and barbed hose port allow for quick, tool-free connection to hoses and vehicle frames. |
| Cost-Effective OEM Solution | Injection-molded design enables mass production with consistent quality, reducing manufacturing costs for automotive clients. |
| Compact & Lightweight | Small footprint and low weight optimize vehicle fuel efficiency and simplify integration into tight engine bays. |
