The MS28775-013 is a military standard O-ring seal designed for use in aerospace hydraulic, fuel, pneumatic, and lubrication systems where reliable leak prevention is essential. Manufactured in accordance with the MS28775 specification, this elastomeric seal provides dependable static and dynamic sealing performance in demanding aircraft operating environments.

Precision molded to meet strict dimensional requirements, the MS28775-013 is engineered to maintain a secure seal under varying pressure and temperature conditions while resisting compression set and fluid leakage. It is commonly installed in valves, pumps, actuators, fittings, and other aircraft fluid system components where maintaining system integrity is critical to safe operation.

Constructed from a fuel- and hydraulic-fluid-resistant elastomer, this O-ring is suitable for a wide range of approved aerospace applications when installed according to OEM maintenance procedures. During scheduled inspections, seals should be examined for cuts, cracking, flattening, hardening, or other signs of deterioration and replaced as required to preserve system performance.

This product is supplied as a 10-piece pack, making it a convenient choice for maintenance, repair, and overhaul (MRO) operations requiring multiple replacement seals.
