Alcoa Fastening Systems Qualifies SAE AS5550 Fluid Fitting

TORRANCE, Calif.--Alcoa (NYSE:AA) announced today that its Alcoa Fastening Systems (AFS) successfully qualified its RFKA9900-13 (SAE AS5550) flareless, plug-in union, Ring Locked fitting series for use on the 787 Dreamliner. This high-pressure titanium hydraulic adapter was selected by Boeing for its lightweight construction and dual seal protection, providing up to 49% weight savings over the previous design for this application. Each aircraft is expected to employ over 120 of these parts.

"This fitting is designed with a 20º metal-to-metal seal, which is the primary seal between the fitting and mating port, and also incorporates an elastomeric o-ring that acts as a secondary or back-up seal," stated Doug Pyle, AFS' Product Management Manager for North America. "The design provides a very desirable, leak-proof, separable port-to-tube connection."
