Pneumatic Push-In Fittings | Air & Water Hose Quick-Release Tube Connectors

Match the fitting size to your tube's outer diameter (OD) — not the inner diameter. For example, a 6mm fitting accepts 6mm OD tubing. Common imperial equivalents: 1/4" ≈ 6mm, 5/16" ≈ 8mm, 3/8" ≈ 10mm, 1/2" ≈ 12mm. For stud fittings, also select the thread size that matches your equipment port (e.g., 1/4" BSP or M8 metric).

Push-in fittings of this type are generally rated for working pressures up to approximately 150 PSI (10 bar), though this can vary by tube size and fitting configuration. Smaller tube sizes typically support higher pressures. Always verify the pressure rating for your specific application, especially in safety-critical systems.

These fittings are generally suitable for water and non-corrosive fluid service. For outdoor use, they typically perform well in sheltered or semi-exposed conditions. Prolonged direct UV exposure or contact with harsh chemicals, oils, or solvents may degrade the plastic body over time. For aggressive environments, contact us to confirm suitability.

Yes. Stud variants are available in both metric threads (M5, M6, M8, M10, M12, M14, M16) and BSP imperial threads (1/8", 1/4", 3/8", 1/2"). Select the thread type and size that matches your valve, cylinder, or manifold port. If your equipment uses NPT threads, contact us to confirm compatibility before ordering.

These fittings are designed for semi-rigid plastic tubing — polyurethane (PU), nylon (PA), and polyethylene (PE) are the most common compatible types. Very soft or highly flexible tubing (such as silicone) may not seal reliably because the collet requires a firm tube wall to grip. Check your tubing's hardness and OD tolerance before use.

To disconnect: press the collet ring (the outer ring at the tube entry point) firmly inward toward the fitting body, then pull the tube straight out simultaneously. Do not twist or yank — a smooth, straight pull with the collet fully depressed releases the tube cleanly without damaging the fitting or tube end.

• Straight — inline connection, same tube size both ends
• Straight Reducing — inline connection between two different tube ODs
• L-Shape (Elbow) — 90° direction change; useful in tight panel spaces
• T-Shape — splits one line into two equal-size branches
• Y-Shape — angled branch split; lower flow restriction than T in some layouts
• X-Shape (Cross) — 4-way equal connection
• Multiple T (4-way) — one inlet, three outlets
• Blanking Plug / Cap — seals an unused tube port or fitting port
• Reducing Plug — reduces a larger port to accept a smaller tube
• Male / Female Stud — connects tubing directly to a threaded port on a valve, cylinder, or manifold

Yes, push-in fittings are generally designed for multiple connect/disconnect cycles. However, if the tube end becomes scratched, deformed, or cut unevenly, it may not reseal reliably. Always re-cut the tube end cleanly and squarely before reinserting into a reused fitting to ensure a leak-free seal.
