Pneumatic Push-In Elbow Fittings — Instant 90° Connections for 4mm & 6mm Air Lines

If you've ever wrestled with a leaking air line or spent too long routing tubing around tight corners in a pneumatic system, you know how much a reliable elbow fitting matters. These pneumatic push-in elbow fittings are built for engineers, automation technicians, and DIY builders who need fast, secure 90° tube connections without specialized tools.

Each fitting features a push-in collet mechanism that accepts standard 4mm (approx. 5/32") or 6mm (approx. 1/4") OD pneumatic tubing, with a threaded male port in M5 or M6 metric sizes. The compact elbow body allows tubing to exit at a right angle, making it ideal for space-constrained panel builds and machine enclosures. Available in quantities of 1, 2, 3, 5, 10, or 30 pieces per order.

Typical applications include pneumatic control panels, robotic end-of-arm tooling, compact cylinder circuits, and DIY air-powered automation projects where routing tubing in a straight line isn't practical. These quick-connect air fittings for 4mm and 6mm hose reduce assembly time and make future maintenance straightforward.

🔗 Compatibility: Fits standard PU, PA, and PE pneumatic tubing with 4mm or 6mm outer diameter. Port threads are M5 or M6 metric — verify your component's port size before ordering.

⚠️ Note: Tube outer diameter and port thread size vary by variant. Please confirm both dimensions against your system specs before adding to cart.

✅ Key Features of These Pneumatic Push-In Elbow Fittings

⚡Tool-Free Push-In Installation — Insert the tube until it clicks into the collet; no clamps, crimping tools, or adhesives needed, cutting assembly time significantly on pneumatic control panels.
📐90° Elbow Body Design — The right-angle configuration lets you route 4mm or 6mm air lines cleanly around corners and through tight enclosures without kinking the tubing.
🔩Metric M5 & M6 Port Options — Threaded male ports in M5 and M6 metric sizes cover the most common pneumatic valve and micro-cylinder port standards used in automation and robotics.
🔄Reusable & Releasable — Press the collet ring to release the tube without damaging the fitting, making these quick-connect air fittings easy to reconfigure during prototyping or system changes.
🛡️Durable Fitting Body — Constructed from engineering-grade materials typically used in pneumatic push-in fittings, offering resistance to the pressures and temperatures found in standard compressed-air systems.
📦Flexible Quantity Options — Order from 1 to 30 pieces in a single SKU, so you can grab a spare for a repair job or stock up for a full panel build without overpaying for bulk minimums.

❓ Frequently Asked Questions

How do I choose the right tube size and port size?

Match the tube size (Ø4mm or Ø6mm) to your pneumatic tubing's outer diameter. Match the port size (M5 or M6) to the threaded port on your valve, cylinder, or manifold. For example, if your tubing is 4mm OD and your component has an M5 threaded port, select the Ø4mm – M5 variant. When in doubt, measure the port thread with a thread gauge or check your component's datasheet.

What is the maximum working pressure for these fittings?

Pneumatic push-in elbow fittings of this type are generally rated for working pressures up to approximately 150 PSI (approx. 10 bar). Always verify the pressure rating against your specific system requirements before installation. If your system operates near or above this range, contact us to confirm suitability.

Can these fittings be used outdoors or in humid environments?

These fittings are typically constructed from materials that offer reasonable resistance to moisture. For prolonged outdoor exposure or high-humidity industrial environments, we recommend confirming the body material for your specific variant and applying PTFE tape to the threads to prevent corrosion at the joint. Contact us to confirm material specs if needed.

Are these fittings compatible with standard pneumatic tubing brands?

Yes. These push-in fittings are designed to work with standard polyurethane (PU), nylon (PA), and polyethylene (PE) pneumatic tubing with 4mm or 6mm outer diameters — the most common tubing types used in pneumatic automation. The M5 and M6 port threads are metric standard (ISO) and compatible with most pneumatic valves, cylinders, and manifolds from major brands.

How do I release the tubing from the fitting?

To release the tube, depressurize the air line first, then press the collet ring (the outer ring around the tube entry point) inward while simultaneously pulling the tube straight out. The collet releases its grip on the tube, allowing clean removal without damaging either the tube or the fitting.

Do I need thread sealant when installing these fittings?

In most cases, applying PTFE thread tape (plumber's tape) to the male threads before installation is recommended to ensure an airtight seal and prevent micro-leaks, especially in systems operating above 60 PSI. Wrap the tape 2–3 times in the direction of the thread before screwing the fitting into the port.

What is the difference between M5 and M6 port sizes?

M5 refers to a 5mm metric thread diameter, commonly found on smaller pneumatic valves, solenoids, and micro-cylinders. M6 refers to a 6mm metric thread diameter, used on slightly larger components. Check your equipment's port specification or measure the thread diameter before ordering to ensure the correct fit.
