The Festo NPQH-D-Q6-Q4-P10 is a straight push-in reducer nipple used to connect two pneumatic tubes of different diameters. It allows a direct connection between a 6 mm tube and a 4 mm tube without the need for adapters or additional fittings. This makes it worthwhile in compact air systems where tube sizes change between components. It is generally used in control cabinets, machinery, and automation systems where clean, simple airline routing is required.

Core Capabilities of the Festo 578329 Pneumatic Straight Tube-to-Tube Reducer Nipple

Both ends of this fitting use push-in connections, allowing tubing to be installed quickly without tools. Once inserted, the tube is held securely and sealed to prevent air leakage.

  • Push-in connection on both sides.
  • Reduces from a 6 mm tube to a 4 mm tube.
  • Straight, in-line design.
  • No threading or sealing tape needed.
  • Saves time during installation.

Designed for Pneumatic Systems

The NPQH series is designed for compressed air applications where reliability matters. The fitting maintains a stable connection under normal operating pressure and vibration, helping keep air lines neat and secure.

Applicable Areas of the Reducer

It works well when upgrading or modifying existing systems that already use different tube diameters.

  • Pneumatic control panels
  • Industrial automation equipment
  • Assembly and packaging machines
  • Air distribution lines with mixed tube sizes
