2 3 Way 1 4" Bsp Air Line Hose Compressor Y Splitter Coupling Connector Airline

PH connectors grip the inside diameter of the pipe — measure the bore of your hose. PP connectors grip the outside diameter — measure the outer wall of your pipe. Using the wrong series will result in a loose or non-sealing fit, so confirm your measurement before selecting a size.

The number indicates the compatible pipe diameter in millimeters. PH20 fits 8mm ID pipe, PH30 fits 10mm ID pipe, and PH40 fits 12mm ID pipe. The same numbering logic applies to the PP (outer diameter) series.

These connectors are designed for standard workshop compressed air circuits. Working pressure ratings vary by variant — contact us to confirm the maximum rated pressure for your specific size before use in high-demand applications.

Standard push-fit and threaded connectors are suitable for most workshop uses where lines are not subject to constant vibration. The self-locking plastic-steel composite variants add a mechanical locking feature that prevents the connection from loosening under vibration or repeated pressure cycling — recommended for fixed installations or high-cycle environments.

No — BSP thread sizes are not interchangeable without an adapter. Select the thread size that matches your compressor port or manifold exactly. The 1/4"-1/2" Thread Fittings variant is a reducer fitting that bridges these two sizes if you need to connect mismatched ports.

For a single compressor feeding two tools, one 2-way Y splitter is sufficient. If you need to run three tools or branches simultaneously, choose the 3-way variant. For a full workshop installation with multiple drop points, the 5-pack or 10-pack options offer better value.

Yes — the range includes both female thread (e.g., 1/4" Female Thread 2 Way) and male thread (e.g., 1/2" Male Thread 2 Way) variants. Match the fitting gender to the opposite gender on your compressor or manifold port for a correct connection.
