PIN-LOK Pneumatic Quick Couplings – Series PIN-LOK
The PIN LOK Pneumatic quick couplings from POOLKE Series PIN-LOK are developed for compressed-air applications where secure connection and reliable operation are especially important. Compared with standard pneumatic quick couplings, the PIN-LOK design adds a mechanical locking feature that helps reduce the risk of unintended release during equipment movement, vibration or frequent hose handling.
Series PIN-LOK is available in multiple body sizes corresponding to the 310, 430 and 550 coupling families, giving users greater flexibility when selecting different flow capacities and connection dimensions. Male thread, female thread and hose barb versions are available, together with various NPT thread and hose sizes for different pneumatic piping layouts. The PIN LOK Pneumatic quick couplings combine the convenience of quick connection with an added locking function, making them suitable for industrial air systems where stable engagement and operational security are required.
