The QKD156 single shut-off industrial steel air pneumatic quick coupling is a type of air fitting that is used to connect and disconnect pneumatic tools and equipment quickly and easily. The coupling is typically made of steel and has a one-way valve that allows air to flow through the fitting when it is connected to another fitting or tool.
The single shut-off feature means that only the socket end of the coupling is valved, which allows for easy disconnection without needing to turn off the air supply. This makes the coupling ideal for use in industrial and commercial settings where quick and frequent connections and disconnections are required.
The industrial steel construction of the coupling ensures durability and reliability, even in harsh environments or under heavy use. The quick coupling may also have a locking mechanism to secure the connection between the male and female ends, providing added safety and preventing accidental disconnections.
