Size Package: You will receive 15 pieces of air push connectors. Each connector measures 36 x 8 mm (L x W), suitable for pipes with an outer diameter of 8 mm / 5/16 Inch. Material: The direct push air line connector is made of PBT plastic, which has good wear resistance and pressure resistance. It can increase mobility, reduce hose stress, and is not easy to crack after longterm use, ensuring the service life. Dustproof and Protective: The air push connectors provide dust protection for air pipes, preventing dust from entering the system and keeping equipment and pipelines clean and hygienic. Good atmospheric pressure resistance makes it not easy to loosen or fall off during work, which can ensure the sealing of pneumatic or hydraulic systems and effectively prevent gas or liquid leakage. Easy to Use: The pushtoconnect fitting plug provides simple and fast pipe connections, and no special tools are required for installation. Insert the plug into the joint opening that needs to be closed, and push the pipe until it makes a 'click' sound to make it firmly fixed. Why you need it and how it helps: Quick, tool connections save time in assembly and maintenance. Durable PBT construction reduces wear and crack risk during longterm use. Designed for 8 mm outerdiameter hoses to ensure a secure, reliable seal. Dust protection helps keep pneumatic or hydraulic systems clean and leak. Applications and use scenarios: Workshop and garage: rapidly connect or air lines for pneumatic tools, spray guns, or blowoff setups, enabling efficient workflows. DIY projects and home garages: set up or modify small pneumatic circuits for cleaning, cooling, or airassisted processes without tools. Automotive and light industrial tasks: create or quickdisconnect lines in pneumatic or hydraulic systems that use 8 mm hoses, maintaining system integrity and reducing hose stress.
