AW971 Series Flexible Threaded Couplings

The AW971 Series Flexible Threaded Couplings are engineered for aerospace fluid-line systems, providing reliable high-current capability and lightning protection. These self-locking couplings are designed to interface with AS902 ferrules (AS1650 compliant) and support misalignment and axial movement in demanding aerospace applications.

Key Features & Benefits:

• Threaded coupling design, sizes –08 through –64

• High-current and lightning-capable (tested per ARP5416)

• Self-locking, no lock wire required

• Operating pressure: 125 PSIG; proof: 250 PSIG; burst: 375 PSIG

• Operating temperature: -65°F to 200°F (dependent on O-ring material)

• Capable of 4° total misalignment in joint

• Approximately 0.25 inch of axial movement between ferrule faces

• Available in Aluminum

These couplings are ideal for aerospace fluid systems where electrical bonding, movement accommodation, and lightning protection are critical. AdelWiggins’ AW971 Series Flexible Couplings combine precision manufacturing, rigorous testing, and decades of aerospace experience to ensure dependable performance in the most challenging environments.
