The QD-INDMC4-4F is a standard industrial-grade pneumatic air coupler designed for general purpose compressed air applications. It features a 1/4-inch body size conforming to the Industrial Interchange standard (often referred to as Type M or MIL-C-4109). This profile is the most common in the industry, ensuring compatibility with a vast array of existing air plugs and tools found in manufacturing facilities, automotive shops, and maintenance departments.
The unit is equipped with 1/4-inch Female National Pipe Threads (FNPT), allowing for direct installation onto male-threaded air hoses, hard piping, or tool inlets. The coupler utilizes a manual sleeve mechanism; to connect, the user must pull back the sleeve, insert the plug, and release the sleeve to lock the ball bearings into the plug's groove. This manual operation provides a positive lock and prevents accidental disconnection. Constructed typically from zinc-plated steel, the coupler offers resistance to mechanical stress and corrosion, making it suitable for environments with standard humidity and wear factors. It is rated for standard shop air pressures, typically up to 300 PSI, and includes a Buna-N seal for leak-free performance.
