304 Stainless Steel Y-Type Push-to-Connect Pneumatic Fittings — Split Your Air Line Without Leaks
When you need to branch a single compressed-air or pneumatic line into two paths, a loose or corroded fitting is the last thing you want. Machinists, automation technicians, and serious DIYers who build pneumatic circuits know that a leaky junction wastes pressure, slows actuators, and creates frustrating troubleshooting sessions. These 304 stainless steel Y-type push-to-connect pneumatic equal connectors are built for exactly that job — delivering a secure, tool-free split in your air line that holds under pressure.
Each piece is a single Y-shaped equal connector machined from 304 stainless steel, with push-fit collet ports on all three legs. Available in five outer-diameter sizes — PY-4mm (≈5/32"), PY-6mm (≈1/4"), PY-8mm (≈5/16"), PY-10mm (≈3/8"), and PY-12mm (≈1/2") — to match standard pneumatic tubing. Order in quantities of 1, 2, 5, or 10 pieces depending on your project scale.
Typical use cases include splitting air supply lines in automated assembly fixtures, routing compressed air to dual cylinders in DIY pneumatic presses, and building clean branch points in workshop air distribution systems — anywhere a reliable push-fit Y-connector for pneumatic tubing is needed.
Verify your tubing OD before ordering. The PY size number refers to the tubing outer diameter (e.g., PY-6mm fits 6mm OD tubing). If you are unsure of your tubing size, measure the outside diameter with calipers before selecting a variant.
Compatible with: PU, PA, and PE pneumatic tubing in matching OD sizes (4mm / 6mm / 8mm / 10mm / 12mm). Designed for standard push-fit pneumatic systems. Not intended for hydraulic or liquid media applications.
✅ Key Features of These Y-Type Push-Fit Pneumatic Connectors
- 304 Stainless Steel Construction — Resists moisture, mild chemicals, and atmospheric corrosion better than standard brass or zinc fittings, making these connectors suitable for outdoor pneumatic lines and humid workshop environments.
- Tool-Free Push-to-Connect Installation — Push tubing in to lock; press the collet ring to release. No wrenches, thread tape, or sealants needed — ideal for rapid assembly of pneumatic circuits and push-fit air line splitters.
- Equal Y-Branch Design — All three ports share the same bore diameter, ensuring balanced airflow distribution when splitting a single supply line into two equal branches without pressure drop bias.
- Five Size Options (4mm–12mm OD) — Covers the most common pneumatic tubing outer diameters used in automation, robotics, and workshop air systems, from compact 4mm lines up to 12mm main supply runs.
- Reconnectable Collet Mechanism — The internal collet grip allows tubing to be disconnected and reconnected multiple times during system layout and testing, reducing waste during prototyping of pneumatic branch circuits.
- Flexible Quantity Options — Available in 1, 2, 5, or 10-piece sets so you can order exactly what your project requires, whether it's a single repair or stocking spares for a multi-station pneumatic system.

❓ Frequently Asked Questions
How do I choose the right size push-fit pneumatic fitting?
Match the PY size to your tubing's outer diameter (OD). PY-4mm fits 4mm OD tubing (≈5/32"), PY-6mm fits 6mm OD (≈1/4"), PY-8mm fits 8mm OD (≈5/16"), PY-10mm fits 10mm OD (≈3/8"), and PY-12mm fits 12mm OD (≈1/2"). Use calipers to measure your tubing OD if you are unsure — do not rely on the tubing's labeled inner diameter.
What tubing materials are compatible with these Y-type fittings?
These push-to-connect fittings are generally compatible with polyurethane (PU), nylon (PA), and polyethylene (PE) pneumatic tubing of the matching outer diameter. Confirm that your tubing's wall thickness and hardness are within the fitting's grip range before use in pressurized systems.
Can these stainless steel fittings be used outdoors or in corrosive environments?
Yes. 304 stainless steel provides good resistance to moisture, mild chemicals, and atmospheric corrosion — making these connectors suitable for outdoor pneumatic circuits and humid industrial environments. For exposure to strong acids, chlorides, or aggressive chemicals, contact us to confirm suitability before ordering.
What is the maximum working pressure for these push-fit connectors?
Working pressure typically ranges up to approximately 0.8–1.0 MPa (≈116–145 psi) for push-fit pneumatic fittings in this size range under normal operating conditions. Actual rated pressure depends on the specific size and tubing type. Contact us to confirm the rated pressure for your selected variant before use in high-pressure applications.
Do I need any tools to install these Y-type push-to-connect fittings?
No tools are required. Push the tubing firmly and squarely into the port until it seats fully — you will feel it click into the collet. To disconnect, press the collet ring inward while pulling the tubing out. Always cut tubing ends cleanly and squarely (use a tube cutter, not scissors) for a reliable, leak-free seal.
How many fittings should I order — 1, 2, 5, or 10 pieces?
For a single repair or prototype branch point, 1–2 pcs is generally sufficient. For small pneumatic panel builds or systems with several Y-junctions, 5 pcs is a practical quantity. The 10-pcs option offers the best per-unit value for larger installations, production fixtures, or keeping spares on hand for maintenance.
Are these fittings reusable after disconnecting the tubing?
In most cases, yes — push-fit pneumatic fittings can be reconnected multiple times. However, repeated disconnection may gradually reduce the collet's grip strength over time. Inspect the collet teeth and internal O-ring for wear before reusing in critical or high-cycle pressure applications.
