Product Description
The 910778 is a preformed packing (backup ring) designed to prevent O-ring extrusion in high-pressure hydraulic glands. This elastomeric seal sits behind the primary O-ring in MIL-G-5514 grooves, protecting it from pressure-induced displacement during static and dynamic applications. Commonly specified to MS28774 standards, the 910778 maintains seal integrity in aircraft hydraulic systems operating at elevated pressures.
Installation requires correct orientation and groove dimension verification per the applicable maintenance manual. Essential for reliable hydraulic assembly performance in general and commercial aviation.
