The Airflow Coupling is the original quick release "PCL" with around 75 years of design enhancement. This product, along with the Standard Adaptor, is still manufactured in the UK to the highest possible standards, with the "Made in Sheffield" Airflow series now a benchmark in the UK for quality and reliability.


Suitable for most compressed air applications - particularly fixed applications where the coupling is used over a workbench and a single action is preferred.
