Festo NPQE-DK-G18-Q4-P10 Pneumatic Fitting

Model Identifier NPQE-DK-G18-Q4-P10
Official Part Number 8112971
GTIN Standard 4052568569013

Technical Overview

Miniature straight fitting for 4mm O.D. tubing with G1/8 male thread. Nickel-plated brass body supports vacuum and positive pressure (-0.95 to 8 bar).

Key Features

  • Miniature straight design optimizing layout footprint in high-density pneumatic manifolds
  • G1/8 male threaded port fitted with an aluminum TPEE sealing ring
  • Push-pull principle connection for standard 4mm O.D. pneumatic tubing
  • Wide-ranging operating pressure from -0.95 bar up to 8 bar
  • Rated for ambient and operating medium temperatures between -5 °C and 60 °C
  • Nickel-plated brass housing providing CRC1 low corrosion resistance

Dual-capable pressure envelope supporting both vacuum (-0.95 bar) and positive pressure (up to 8 bar) with a space-saving internal hex drive.

Industrial Applications

1. Compact Robotics End-Effector Routing

Connecting tight-tolerance pneumatic supply lines to compact robotic grippers where mechanical space is severely restricted.

Problem Solved

The miniature straight design and internal hex mounting permit the fitting to be installed deeply into confined manifolds without requiring external wrench clearance.

3. Automated Vacuum Fixturing and Test Jigs

Supplying modular pneumatic routing in electronic testing systems that utilize both air clamps and suction mechanisms.

Problem Solved

The dual-pressure capability safely supports vacuum systems down to -0.95 bar, allowing operators to use identical fittings for positive clamping and negative-pressure suction.
