What is the difference between PCL Standard and XF Euro adaptor profiles?
Standard adaptors (commonly referred to as PCL’s air fittings) are the standard UK profile, these adaptors are longer than Euro adaptors. A standard adaptor is suitable for applications up to 14 bar / 200 psi, and will connect to PCL’s Airflow, Vertex, Safeflow and Non corrodible couplings – which coupling you decided to choose is down to whether your application is fixed, trailing hose, require a safety coupling or if it is being used in damp environments.
Standard Adaptor
Euro style air fittings such as XF-Euro Adaptors are the standard use in Europe and the Far East. PCL’s XF-Euro adaptors have a higher flow rate than the UK profile as they have a larger nominal bore - this is the internal diameter of the hole that runs through the length of the coupling or adaptor – this makes it less restrictive and ideal for use with larger air tools such as ¾” or 1” Impact Wrenches, and other high flow applications up to 35 bar / 508 psi.
XF-Euro Adaptor
The Standard and XF-Euro profiles do not interchange, for example, an XF-Euro adaptor will not fit into a UK style coupling. A standard adaptor will loosely fit into an XF-Euro Coupling, however this will result in a loss of air flow, so it important you have the correct profile.

Both PCL’s standard and XF-euro profiles come in a large range of thread sizes, and are available with an integral hose tailpiece, male or female BSP thread. Unsure what thread size you require? Take a look at our handy guide.
