Pneumatic Push-in T-Shape 3-Way Fitting — Air Water Tube Connector PE4–PE16 & Reducing

Match the fitting size to your tube's outer diameter (OD). For example, PE6 fits 6mm OD tubing (approximately 1/4"), PE8 fits 8mm OD tubing (approximately 5/16"), and PE10 fits 10mm OD tubing (approximately 3/8"). For reducing T fittings (PEG series), the numbers indicate the port sizes — e.g., PEG8-6 has two 8mm ports and one 6mm branch port. Always measure your tube OD before ordering.

Push-in pneumatic fittings of this type are generally rated for working pressures up to around 100–150 PSI (approximately 7–10 bar) depending on the tube material and size. For safety-critical or high-cycle applications, always verify the pressure rating against your specific system requirements before installation.

Yes. These push-in T connectors are generally compatible with both compressed air and water lines. They are commonly used in pneumatic systems, irrigation setups, and light fluid transfer applications. Confirm compatibility with your specific fluid type and operating pressure before use in non-air applications.

PE sizes (e.g., PE4, PE6, PE8) are equal-bore T fittings where all three ports share the same tube OD. PEG sizes (e.g., PEG8-6, PEG10-8) are reducing T fittings where two ports are one size and the branch port is a different (smaller) size — useful when you need to branch a larger main line into a smaller secondary line within a single push-in 3-way fitting.

To install: cut the tube end cleanly and squarely, then push it straight into the fitting port until it clicks and seats firmly — no tools required. To release: press the collet ring inward toward the fitting body while simultaneously pulling the tube out. A clean, square tube cut is essential for a reliable, leak-free seal.

These fittings are generally compatible with standard pneumatic tubing including polyurethane (PU), nylon (PA), and polyethylene (PE) tubes. The tube outer diameter must match the fitting size exactly. Soft or oversized tubing may not seat correctly and can cause leaks — always use tubing that meets standard OD tolerances.

This product is available in 1, 2, 5, 10, 20, and 50 piece packs. For a single repair or prototype build, 1–2 pcs is typically sufficient. For pneumatic panel installations, production line builds, or workshop stock, ordering 10–50 pcs generally offers better value per unit and ensures you have spares on hand.
