The high precision pressure regulator valve controls the pressure inside the cooler. Protects your engine from overheating and burning!
The compression valve seal is made of silicone rubber with exceptional heat and chemical resistance.
The metal part of the cap is made of rust-resistant stainless steel, and the exterior is coated with a special black plating for added durability.
When the spring of each valve is compressed (installed), the spring pressure gradually decreases gradually Estimated reduction of approximately 0.1kg/cm2 per year. Therefore, we recommend replacing the radiator cap after vehicle inspection.
Please check the shape and size carefully before purchasing.
