In order to ensure a leak-free seal under high pressure, the double headed M22 brass spiral connector is equipped with a high-quality O-ring. The seal is made of high-quality elastic material, has resilience and wear resistance, can maintain a tight sealing effect under high pressure conditions, effectively prevent medium leakage, and ensure the safe and stable operation of the system. The connector uses high-quality brass as the main material. Brass has corrosion resistance, good mechanical strength and suitable processing performance. It shows durability and stability in a variety of chemical media, especially in acidic and saline-alkali environments. This enables the double headed M22 brass spiral connector to maintain a long operating life and stable connection performance in complex and changeable industrial cleaning environments. The outside of the connector nut is also specially covered with a wear-resistant and non-slip plastic sleeve. This plastic sleeve not only improves the comfort and efficiency during operation, but also keeps the hand feel smooth and stable even in long-term or frequent operations.
