Uflow VO Series One‑Touch PU Fittings

Compact & Captivating Design
Engineered for space‑saving pneumatic systems, Uflow’s VO fittings combine aluminum/plastic threaded bodies with a 360° rotating nipple design—ideal for flexible routing and tight installations.

Full‑Bore Flow & Airtight Seal
Full-bore internal design ensures smooth, low-resistance airflow. The stainless-steel collet and NBR seals guarantee secure, reliable, leak-free connections.

Robust & Vibration‑Resistant
Rugged collet design and PTFE-coated male taper threads maintain connection integrity, even under vibration or movement.

Versatile & Easy to Use
Perfectly compatible with both nylon and PU tubing (Ø 4–16 mm), VO fittings support a max working pressure of 10 bar and operate from –10 °C to +60 °C. Quick “push-in” tube insertion and tool-free release make assembly fast and maintenance simple.

360° Threaded Nipple Rotation
Each threaded nipple features a full 360° plastic rotatable portion, enabling easy installation—even in tight orientations.

Available Configurations

Uflow offers a full range of push-to-connect fittings:

  • Straight unions & reducers (same/ different diameters)

  • Elbows & elbow reducers (90° orientation)

  • Tee, Y-tee, cross connectors, including multi‑distributor unions

  • Swivel options: single, double, triple

  • Threaded adapters: male, female, bulkhead variants

  • Plugs and branch tees, accommodating BSPT/BSP/NPT threads in M5, 1/8″, 1/4″, 3/8″, 1/2″ sizes.

Why Uflow VO Fittings?

  • High flow performance: Smooth full-bore design reduces pressure drop.

  • Universal compatibility: Works with Nylon and PU tubing.

  • Flexible installation: 360° rotation and multiple orientations ease layout.

  • Long-lasting durability: Stainless steel collet, PTFE-coated threads, vibration resilience.

  • Wide utility: Fits across pneumatic cylinders, valves, FRL units, control panels, and compressed air lines.

Applications

Widely used in:

  • Pneumatic cylinders & solenoid valve panels

  • Air preparation units (FRL)

  • Complex pneumatic control circuits

  • Industrial automation, F&B, packaging, machine tools
