【Non Return Check Valve】Stops air from flowing back to the air pump or air compressor, keeping it in the line. Direction markings on the valve body clearly show the direction of airflow. Recommended pressure: 0~1.0Mpa
【Pneumatic Valve Body】Made of nickel-plated copper and PBT plastic material, with smooth surface, high hardness, high pressure resistance, anti-corrosion and long service life. There is a sealing ring inside, anti-leakage, strong sealing, safe to use
【Stainless Steel Card Spring】Connected tightly, not easy to unbuckle, the gas pipe is firm and not loose, no air leakage, repeated pulling and inserting does not affect the card spring to tighten the strength
【Application】Suitable for hose, PU tube, nylon tube. Widely used in gas equipment, CNC machine tools, air lines, pneumatic tools, automatic assembly lines and other industrial equipment
【Easy to Connect Air Tube】Press the valve cap, grab the air tube, slowly push it into the check valve fitting, the air tube will be locked by the spring washer. Note: when connecting the air tube to the check valve, make sure that the air tube is pushed tightly. This means that the internal air tube has passed through the sealing ring. If the air tube does not pass through the sealing ring, leakage or bursting may result
