Under its distribution agreement, Eaton will supply AAR a variety of products that support aircraft fluid distribution including, Teflon hose assemblies, quick disconnect couplings, debris-monitoring devices, pressure switches and transducers, pneumatic ducting systems, clamps and flanges.

"Eaton and AAR have extensive experience as military suppliers, and now we are working together to better serve the needs of the Defense Logistics Agency," said Einar Johnson, Vice President of Customer Solutions and Services for Eaton's Aerospace Group.
