What is the maximum working pressure for these fittings?

These push-in fittings are generally rated for pneumatic systems operating up to approximately 150 PSI (approximately 10 bar) at room temperature. Actual ratings may vary by size — contact us to confirm for your specific variant.

Can these fittings be used outdoors or in humid environments?

These fittings are typically made from engineering-grade plastic (such as PA or POM) which offers good resistance to moisture and mild chemicals. They are generally suitable for indoor industrial and workshop use. For prolonged outdoor or corrosive environments, contact us to confirm material compatibility.

What tubing standards are compatible with these fittings?

These fittings use metric outer-diameter (OD) sizing and are compatible with standard pneumatic polyurethane (PU), nylon (PA), and polyethylene (PE) tubing of the corresponding OD. They are not designed for NPT or BSP threaded connections — they are push-to-connect style only.

How do I release the tubing from a push-in fitting?

To release the tube, press the collet ring inward toward the fitting body while simultaneously pulling the tube straight out. Do not twist or yank the tube, as this can damage the collet teeth. Depressurize the line before disconnecting.

Which size should I choose for a 1/4 inch air line?

Standard 1/4 inch OD tubing corresponds to approximately 6mm metric OD. Select any variant with a 6 in the size designation for the port you are connecting to (e.g., 6-4-6 mm or 8-6-8 mm for the 6mm ports).

Reducer Tee Push-In Fittings — Split and Reduce Your Pneumatic Air Lines in One Step

When your pneumatic system needs to branch off to a smaller line — or merge two different tube sizes into one — a standard straight fitting just won't cut it. Machinists, automation technicians, and workshop DIYers dealing with mismatched air line diameters know the frustration of leaks, adapters stacking up, and wasted time. These reducer tee push-in fittings solve that problem with a single, compact connector.

Each fitting is a three-port reducer tee in a push-to-connect design. The size format is Branch–Center–Branch (e.g., 6-4-6 mm means two 6mm branch ports and one 4mm center port). Available sizes range from 4mm to 16mm (approximately 3/16" to 5/8") across both ports, covering the most common metric pneumatic tubing diameters. Compatible tubing materials include polyurethane (PU), nylon (PA), and polyethylene (PE). Choose from 1, 5, 10, or 20-piece quantities to match your project or restocking needs.

Typical applications include pneumatic control panels where branch lines step down to solenoid valves, robotic end-of-arm tooling with mixed tube sizes, compressed air distribution in woodworking and metal fabrication shops, and inline flow splitting for vacuum or blow-off circuits. Long-tail use cases like pneumatic reducer tee connector for automation and push-in air fitting for mixed tube diameter are exactly what this fitting is built for.

ℹ️ Compatibility Note: These are metric OD push-to-connect fittings. Verify your tubing outer diameter before ordering. Size format: Branch–Center–Branch (e.g., 8-6-8 mm = two 8mm ports + one 6mm port). Not compatible with NPT or BSP threaded connections.

✅ Key Features of These Reducer Tee Push-In Fittings

🔀True Reducer Tee Design — Splits one air line into two different diameters in a single fitting, eliminating the need for separate reducers and tees stacked together.
⚡One-Touch Push-In Connection — Insert the tube and it locks instantly — no tools, no thread tape, no wrenches. Ideal for rapid assembly in pneumatic reducer tee connector applications.
📐Wide Size Range (4–16mm) — Covers the most common metric pneumatic tubing ODs from 4mm (approx. 3/16") to 16mm (approx. 5/8"), with 15 size combinations available across both ports.
🔒Collet-and-O-Ring Seal — The internal collet grips the tube OD while the O-ring provides an airtight seal, maintaining integrity under typical workshop air pressures.
♻️Reusable and Reconfigurable — Press the collet ring to release and reinsert tubing without damaging the fitting, making these suitable for prototype builds and push-in air fitting for mixed tube diameter setups that change over time.
📦Flexible Pack Quantities — Available in 1, 5, 10, or 20-piece packs so you can order exactly what a single repair needs or stock up for a full panel build without overpaying.

❓ Frequently Asked Questions

How do I choose the right reducer tee size?

The size format is Branch–Center–Branch. For example, 6-4-6 mm means the two branch ports accept 6mm OD tubing and the center port accepts 4mm OD tubing. Measure your existing tubing's outer diameter and match it to the port you're connecting to. Common conversions: 4mm approx. 5/32", 6mm approx. 1/4", 8mm approx. 5/16", 10mm approx. 3/8", 12mm approx. 1/2", 16mm approx. 5/8". When in doubt, size up to avoid flow restriction.

What is the maximum working pressure these fittings can handle?

These push-in fittings are generally rated for pneumatic systems operating up to approximately 150 PSI (approx. 10 bar) at room temperature. Actual pressure ratings may vary by port size — larger ports typically handle higher flow but the pressure rating is generally consistent across the range. Contact us to confirm for your specific size if your application is near the upper limit.

Can I use these fittings outdoors or in humid/wet environments?

These fittings are typically constructed from engineering-grade plastic (such as PA or POM) which offers good resistance to moisture, mild oils, and common workshop chemicals. They are generally suitable for indoor industrial and workshop environments. For prolonged outdoor exposure, UV-heavy environments, or contact with aggressive chemicals, contact us to confirm material compatibility before ordering.

What tubing standards are compatible — metric, imperial, or both?

These fittings use metric outer-diameter (OD) sizing. They are compatible with standard pneumatic PU, PA, and PE tubing sold by metric OD (e.g., 6mm OD, 8mm OD). Many US-sold pneumatic tubes are also available in metric OD, so compatibility is generally straightforward. These are not designed for NPT or BSP threaded connections — they are push-to-connect only with no threaded ports.

How do I release the tubing once it's inserted?

To release the tube: (1) Depressurize the air line first. (2) Press the collet ring firmly inward toward the fitting body. (3) While holding the collet in, pull the tube straight out — do not twist. Avoid yanking without pressing the collet, as this can damage the internal teeth. The fitting remains reusable after release.

Which size should I pick for a standard 1/4" air line?

Standard 1/4" OD tubing corresponds to approximately 6mm metric OD. Select any variant that shows a "6" for the port you are connecting your 1/4" line to. For example, 6-4-6 mm connects two 1/4" lines to a smaller 4mm center line, while 8-6-8 mm connects two 5/16" lines to a 1/4" center line.

Are these fittings reusable, and how many cycles can they handle?

Yes, push-in fittings are generally reusable. The collet-and-O-ring mechanism allows repeated insertion and removal without tools. In most cases they perform reliably through many connect/disconnect cycles in typical workshop use. Inspect the collet teeth and O-ring for wear periodically, especially in high-cycle automation applications. Replace if you notice reduced grip or air leakage at the joint.
