Pneumatic Push Fit Connectors Air Hose Speed Push In Fittings PU PE PY PG PEG

Choose based on your circuit layout: PU (straight union) joins two tubes in a straight line. PE (elbow) makes a 90° turn — useful when routing around obstacles. PY (Y-branch) splits one line into two, ideal for feeding multiple tools from one supply. PG (reducing straight) connects two tubes of different outer diameters in a straight run. PEG (reducing elbow) does the same but at 90°. Match the fitting type to the direction and diameter change your layout requires.

Measure the outer diameter (OD) of your tubing — not the inner bore. Common metric sizes are 4, 6, 8, 10, 12, and 16 mm OD. For reducing fittings (PG / PEG), the size code lists larger-to-smaller diameter (e.g., PG10-8 connects 10 mm OD tubing to 8 mm OD tubing). If you are unsure, use a caliper to measure the tube's outside edge before ordering.

These fittings are designed for standard metric OD pneumatic tubing, including polyurethane (PU), polyethylene (PE), and nylon air tubing. The tubing must be cut cleanly and squarely — a ragged or angled cut can prevent a proper seal. They are not intended for braided hose or tubing with non-standard wall thicknesses.

These push-in fittings are rated for typical workshop pneumatic pressures, generally up to 10 bar (approximately 145 psi). Always verify the pressure rating for the specific size variant you select, and ensure your system pressure does not exceed the fitting's rated limit. Do not use in high-pressure hydraulic or steam applications.

Yes. To disconnect, press the collet release ring toward the fitting body while pulling the tubing out. The fitting can be reused multiple times provided the collet and O-ring are undamaged. Inspect the collet teeth and O-ring for wear if you notice reduced grip or minor leaks after repeated use.

No thread sealant or PTFE tape is needed for the tube-to-fitting connection — the internal O-ring provides the seal. However, if a fitting has a threaded port end (such as a male or female BSP/NPT thread variant), apply PTFE tape to that threaded connection before installation into a manifold or valve block.

Ensure the tubing end is cut cleanly and at 90° with no burrs. Push the tube firmly into the fitting until it stops — you should feel it seat against the internal stop. Give the tube a gentle pull to confirm the collet has gripped. If a leak persists, remove the tube, inspect the cut end for damage, trim if necessary, and reinsert. Also confirm the tubing OD matches the fitting size exactly.
