Parker Stratoflex R44151P-08W - Dynatube Connector

Parker Stratoflex invented the Dynatube beam seal fitting to solve the leakage and vibration failures that plagued conventional flared fittings in NASA's rocket programs. The R44151P-08W brings that same technology to 1/4" aircraft tubing circuits, rated to 4,000 psig per MIL-F-85421 / AS85421 and designed for aircraft hydraulic, fuel, and pneumatic system tubing connections. Weld-end connector with a standard 1/4" beam seal port on one end and a weld preparation on the other, suited for installations where one tube end is welded to a manifold or structural member while the other end requires the removable beam seal connection.

Key Features

• 1/4" tube OD Dynatube beam seal connector, rated 4,000 psig per MIL-F-85421 / AS85421
• fatigue-resistant beam seal that maintains integrity under the cyclic loading of flight operations
• field-reusable design that preserves seal integrity through multiple removal and reinstallation cycles
• Weld-end design: 1/4" beam seal on one port, weld preparation on the other
• 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 737/747 flight deck instrument and hydraulic sensing systems, regional jet ECS plumbing, military trainer hydraulic and fuel sensing circuits, and unmanned aerial vehicle (UAV) fuel system tubing. The R44151P-08W is a direct-fit Parker Stratoflex Dynatube component for hydraulic and fuel system plumbing and maintenance applications maintained by certified A&P mechanics and approved MRO facilities.
