Couplings & Adaptors

Why use a Safety Coupling or Adaptor?

Coupling connections are subject to Health and Safety regulations, due to the dangers associated with hose whip. The Health & Safety Guide HSG 39 recommends that for all hoses above 10 mm bore, more than 10 m long or subject to a pressure exceeding 7 bar, the connector should have a self-venting coupling, alternatively an adaptor with a controlled venting action should be used.

The use of a self-vent safety coupling ensures that pressure in the circuit is reduced to a safe level before the coupling and adaptor can be disconnected, this prevents accidental tool operation and uncontrolled whipping of the hose. Not

What is the difference between Airflow and Vertex Couplings?

PCL’s Airflow and Vertex Couplings have many similarities; both feature the distinctive blue silicone band with a steel construction and corrosive resistant, both have the same specifications and are compatible with PCL's Standard Adaptors, however the main difference between the Airflow and Vertex is the application they are used for.

Coupling connections are subject to Health and Safety regulations due to the vibrations associated with air tool use.
