This Draper 3/8" Female Thread PCL Parallel Airflow Coupling is designed for professionals and DIY enthusiasts working with compressed air systems. Its key benefit is providing a positive lock, single-action connection for efficient and reliable airflow, ideal for most compressed air applications. A slight caveat is that it's sold loose, requiring separate purchase of standard adaptors. It features a BSP parallel thread, a maximum airflow rate of 1197L/min (42cfm) at 6.9bar (100 psi), and a maximum working pressure of 13.8bar (200psi).

PCL refers to the type of coupling, known for its positive lock single-action mechanism. Parallel indicates that the thread is straight (not tapered), which is standard for most compressed air fittings.
The maximum working pressure for this coupling is 13.8 bar (200 psi).
No, this coupling features a 3/8" BSP parallel thread. NPT (National Pipe Taper) threads are different and not directly compatible. You would need an adaptor to connect NPT fittings.
No, this coupling is specifically designed for compressed air applications and should not be used with water or other fluids.
This coupling has a 3/8" female thread. You will typically connect it to a male-threaded adaptor, which then connects to your air hose, or directly to a hose end fitting that has the corresponding male thread.
The coupling has a maximum airflow rate of 1197L/min (42cfm) at 6.9 bar (100 psi). Airflow will vary with system pressure.
Ensure the male adaptor is fully tightened onto the female coupling. Check for debris or damage on the sealing surfaces of both the coupling and the adaptor. Verify that the thread type (3/8" BSP parallel) is correct for your application.
Inspect the locking mechanism for any obstructions or damage. Ensure the mating part is a compatible PCL-type coupling designed for single-action locking. If the male adaptor is worn, it may not engage the locking mechanism properly.
Verify that the connected air hose and tools are not restrictive. Ensure the coupling's airflow path is clear of any blockages. Check that the air compressor is providing adequate pressure and volume.
Setup:
To set up the Draper 3/8" Female Thread PCL Parallel Airflow Coupling, ensure the male component (adaptor or tool fitting) is compatible with a 3/8" BSP parallel thread. Screw the female coupling onto the male thread until securely tightened. Connect the compressed air hose to the other end of the coupling or directly to the fitting if it's integrated.
Compatibility:
This coupling is designed for use with standard compressed air adaptors and fittings that feature a 3/8" BSP parallel thread. It is specifically intended for compressed air applications and should not be used with other gases or liquids. Ensure your air compressor and tools operate within the coupling's maximum working pressure of 13.8bar (200 psi).
