Stainless Steel Pneumatic Push Fit Connector Elbow Tee Straight Air Hose Tube

Measure the outer diameter (OD) of your pneumatic tube in millimeters — not the inner diameter. Common sizes are 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, and 16 mm. The fitting collet is sized to grip that specific OD, so using the wrong size will result in leaks or the tube not seating correctly. If you are unsure, use a caliper on the tube itself before ordering.

These fittings use BSP (British Standard Pipe) threads, which are the standard for most pneumatic components outside North America. BSP threads are not directly interchangeable with NPT (National Pipe Taper) threads. If your equipment uses NPT ports, you will need a BSP-to-NPT adapter. Check your valve, cylinder, or manifold documentation to confirm the thread standard before selecting a size.

Yes. The stainless steel body provides meaningful corrosion resistance compared to brass or zinc-alloy fittings, making these a practical choice for damp workshops, outdoor compressed air lines, and environments with oil mist or condensation. For continuous outdoor exposure, ensure the connected tubing is also rated for UV and weather resistance.

Push-to-connect fittings are generally reusable. To release the tube, press the collet ring firmly toward the fitting body while pulling the tube out. Inspect the collet teeth and O-ring seal after each removal — if the collet is deformed or the O-ring is cracked, replace the fitting before reuse to maintain a leak-free connection.

The standard 90° Elbow PV is a passive fitting that simply changes the direction of the air line. The SL variant adds an integrated flow control valve, allowing you to meter or shut off airflow at the fitting itself without installing a separate inline valve. This is useful in space-constrained panels or when you need individual cylinder speed control at the port.

Both muffler types thread into the exhaust port of a pneumatic valve or cylinder to reduce the sharp discharge noise when air is vented. The Cylinder Head Muffler has a taller, cylindrical sintered body that offers slightly higher flow capacity, while the Flat Head Muffler has a lower profile suited to tight spaces. Both are available in 1/8" to 3/4" BSP thread sizes.

The Reducer Straight PG is used when you need to connect two tubes of different outer diameters in a straight line — for example, stepping down from a 10 mm main line to an 8 mm branch. The size designation (e.g., PG10-8) indicates the larger tube OD first, then the smaller. If both tubes are the same diameter, use a standard Straight PU fitting instead.
