ARP820A - Physical & Performance Tests for Type II (-65 to 275 F) O-ring Packings, 3000 psi Hydraulic Service

Details Document Number: ARP820A Revision Number: A Title Physical & Performance Tests for Type II (-65 to 275 F) O-ring Packings, 3000 psi Hydraulic Service Scope This document outlines proposed test methods for the qualification of O-ring packings intended for use in aircraft hydraulic systems utilizing MIL-H-5606 fluid at rated service pressures up to 3000 psi and temperatures ranging from -65 to 275 F. It will also serve as the basis for the future preparation of a complete packing specification after basic elastomer types have been established by capability of performance.
