Breaking expectations.

Rockwell Collins® (formally Kaiser Roylyn) Breakaway Couplings prevent costly damage to the aircraft service panel by separating or “breaking away” should servicing personnel inadvertently drive away from the aircraft prior to disconnecting the service hose. The patented Breakaway Coupling is spliced into the 3/4 inch Potable Water Fill and the Lavatory Rinse/Fill service hoses between the servicing truck and the aircraft connecting coupling. Upon a pull force of approximately 100 pounds, the tab of the internal shear ring breaks, allowing the coupling to separate.


  • Spliced and clamped into ground servicing 1 inch lavatory rinse/fill supply and the 3/4 inch potable water fill supply hose
  • Lightweight anodized aluminum construction for easy handling
  • Coupling nipple and housing separate with a pull force of 100 pounds
  • Field-replaceable shear ring after separation has occurred: Part number 2145-0155
