Product Information
Full details
This Draper 3/8" Thread PCL Coupling with Tailpiece is designed for professionals and DIY enthusiasts working with compressed air systems. Its key benefit is providing a positive lock connection for reliable performance in most compressed air applications, with a caveat that it is sold loose and requires separate components for a complete setup. It features a single-action lock mechanism for ease of use and is built to handle significant airflow and pressure.

Extended Product Information
FAQs
What is a PCL coupling?
PCL (Couplings) Ltd. is a manufacturer of pneumatic quick release couplings. This coupling adheres to their standard design, known for its positive locking mechanism and robust performance in compressed air applications.
Does this coupling come with a female counterpart?
No, this product is sold loose and includes the male coupling with a tailpiece. You will need to purchase a compatible PCL female coupler separately if you do not already have one.
What type of air hose can be used with the tailpiece?
The tailpiece is designed to accept standard pneumatic air hoses. The specific size requirement will depend on the inner diameter of your air hose. A hose clamp is typically used to secure the hose to the tailpiece.
What is the maximum pressure this coupling can handle?
The maximum working pressure for this Draper coupling is 13.8 bar (200 psi).
Can this coupling be used for water or other liquids?
This coupling is specifically designed and rated for compressed air applications. It is not recommended for use with water or other fluids as it may not provide a proper seal and could lead to damage or leaks.
How do I ensure a secure connection?
Push the male coupling firmly into the female coupler until it clicks and locks into place. A secure connection is indicated by the absence of air leaks when the system is pressurized.
What is the airflow rate?
The maximum airflow rate is 1197 Litres per minute (42 cubic feet per minute) at 6.9 bar (100 psi).
Troubleshooting
Air leak at the connection point
Ensure the coupling is securely threaded onto the female connector. Check the condition of the threads on both the coupling and the receiving port. Ensure the female coupler is clean and free from debris. If using a tailpiece with a hose, verify the hose clamp is tight and the hose is properly seated.
Coupling does not lock securely
Verify that you are using a compatible PCL female coupler. Inspect the internal locking mechanism of the female coupler and the external mechanism of this male coupling for damage or obstruction. Ensure the female coupler is rated for the correct pressure and airflow.
Reduced airflow despite correct connection
Check for internal obstructions within the coupling or the connected hose. Ensure the female coupler is not restricted. The maximum airflow rate is dependent on system pressure; ensure adequate compressor output.
Corrosion or damage to the coupling
If significant corrosion or damage is present, the coupling should be replaced to ensure safe and reliable operation. Minor surface rust can sometimes be cleaned, but structural damage requires replacement.
Pros and Cons
Pros
- Provides a secure and reliable connection with its positive lock mechanism.
- Designed for high airflow and pressure, suitable for professional use.
- Standard 3/8" thread makes it compatible with many air tools and hoses.
- Single-action locking is quick and easy to use.
- Durable construction expected from the Draper brand.
Cons
- Sold loose, meaning additional fittings or components may be required for immediate use.
- Specific PCL coupling might not be universally compatible with all non-PCL systems.
- No included instructions for specific setups, requiring user knowledge.
- Plastic components, if present, might be susceptible to damage from impacts.
- May require a specific type of female coupler to engage properly.
Setup, Compatibility & Care
Setup:
This coupling is designed for use with standard 3/8" threaded air hoses and compatible PCL female couplers. Ensure the threads are clean before connecting. Screw the male thread of the coupling securely onto the female thread of the air hose or tool. The tailpiece end is designed to accept a standard air hose, which may require a hose clamp for a secure fit, depending on the hose type.
Compatibility:
- Thread Size: Compatible with 3/8" BSP or NPT threads (verify thread type before purchase as BSP is common in UK/Europe and NPT in North America).
- Coupling Type: Designed to connect with PCL type female couplers. It is recommended to use PCL-compatible female couplers for optimal performance and secure connection.
- Air Systems: Suitable for compressed air systems operating within the specified pressure range (up to 13.8 bar / 200 psi).
Care:
- Regularly inspect the coupling for any signs of wear, damage, or corrosion.
- Keep the connection points clean and free from debris to ensure a good seal.
- Avoid exposing the coupling to harsh chemicals or extreme temperatures that could degrade materials.
- Periodically check that the connection to the air hose is secure, especially if using a clamp.
