Parker Stratoflex R44151P-16 - Dynatube Connector

For hydraulic power unit supply lines, flight control primary system trunk lines, and engine-driven pump outlet circuits on commercial and military aircraft, the Parker Stratoflex R44151P-16 delivers the 1/2" Dynatube beam seal connection required at fittings, valves, and component interfaces. Rated to 3,000 psig per MIL-F-85421 / AS85421, this connector uses the same patented beam seal geometry Parker Stratoflex developed for NASA's high-vibration, high-temperature rocket programs. Standard inline connector for 1/2" tube that installs using a torque wrench, no flaring, brazing, or swaging required.

Key Features

• 1/2" tube OD Dynatube beam seal connector, rated 3,000 psig per MIL-F-85421 / AS85421
• vibration-resistant seal geometry that distributes stress evenly across the sealing zone
• reusability advantage that reduces replacement cost over the service life of the aircraft
• No flaring, brazing, or swaging required, torque-to-install beam seal engagement
• No safety wiring required
• Compatible with Skydrol®, MIL-H-5606, MIL-H-83282, JP-4, JP-8, and aviation fuels
• No flaring, brazing, or swaging required at installation

Applications

The Dynatube beam seal system has logged extensive service on Boeing 747/777 main hydraulic system trunk lines, C-17 main hydraulic power circuits, Airbus A330/A340 primary hydraulic system plumbing, and military transport main hydraulic circuits. The R44151P-16 is a direct-fit Parker Stratoflex Dynatube component for hydraulic power unit supply lines, flight control primary system trunk lines, and engine-driven pump outlet circuits maintained by certified A&P mechanics and approved MRO facilities.
