Product Description
The MS28775-141 is a nitrile rubber O-ring conforming to Military Standard MS28775 (superseded by SAE AS28775). This preformed packing provides static sealing in hydraulic actuators and fluid system glands operating with petroleum-based hydraulic fluids such as MIL-H-5606. The nitrile material, per AMS-P-25732, resists petroleum products across typical aerospace temperature ranges.
Installation requires compatible lubricant application and careful handling to avoid sharp edges that could damage the seal. Verify size and material specifications against the aircraft's Illustrated Parts Catalog (IPC) and follow applicable Aircraft Maintenance Manual (AMM) or Component Maintenance Manual (CMM) procedures for proper installation and gland preparation.
