Quickcoupling twoway pneumatic connector with selflocking mechanism — designed for secure, fast connections between air compressors, air tools, PU hoses, and plastic tubing. Key benefits Fast, secure hookups: Selflocking quick coupling saves time when switching tools or moving between work areas and prevents accidental disconnection under load. Reliable leak prevention: Rust plasticsteel construction and a tightsealing design resist leaks up to the maximum rated pressure of 15 kgf/cm2, suitable for general pneumatic systems. Simple installation and compatibility: Male/female adapter available with 1/4' or 1/2' internal or external thread options to fit common fittings and hose sizes. Durable performance: Engineered to resist erosion and impact damage and to operate reliably in temperatures from 35℃ to 50℃, making it appropriate for industrial automation and demanding jobsite use. What it does for you Reduces downtime by enabling quick tool changes and secure connections without tools. Minimizes air loss and maintenance needs with a tight, corrosionresistant seal. Works with standard thread sizes and common PU hoses and plastic tubes, simplifying inventory and replacements. Key specifications Type: Quick coupling plastic twoway pneumatic connector Connection: Male/female adapter options Thread sizes: 1/4' or 1/2' internal (female) or external (male) Compatible with: PU hose and plastic tube applications, general pneumatic systems, air tools, compressors Maximum pressure: 15 kgf/cm2 Material: Rust plasticsteel construction Temperature range: 35℃ to 50℃ Durability: Resistant to erosion and impact damage Typical applications Construction and maintenance sites: Quickly connect compressors to nail guns, impact wrenches, and other pneumatic tools for fast tool swaps. Industrial automation and assembly lines: Provide reliable, leakresistant hookups for pneumatic actuators and airoperated equipment in production environments. Workshop and garage use: Connect compressors to tire inflators, blow guns, and air brushes without tools and with minimal air loss. Installation and use tips Choose the correct thread size (1/4' or 1/2') and male/female configuration for your hose or port before installation. Inspect sealing surfaces and Orings for debris before connecting to maintain leak performance. Operate within the specified pressure and temperature ranges to ensure long service life. This connector provides a practical, durable solution for fast, secure pneumatic connections in both field and industrial settings.
