The LB rod seal is a lip seal with interference fit at the outer diameter. It is designed for installation in market-specific grooves according to MIL-G-5514 / AS4716 and used in hydraulic actuators in aviation applications, primarily where particularly high sealing performance and wear resistance are required and conventional compact seals do not satisfy the specific demands of the aviation industry. The LB rod seal consists of an NBR lip ring and a PTFE anti-extrusion ring. Among other things, it is characterized by exceptionally high static and dynamic sealing performance which is achieved by optimized seal geometry with two sealing lips located on the static and dynamic side of the seal. A back-up ring on the back of the seal provides improved extrusion resistance. When appropriate materials are selected, the LB rod seal is suitable for wide temperature ranges. Its good wear resistance and resulting service life can be significantly enhanced as well by selecting suitable materials.• Exceptionally high static and dynamic sealing performance.• Good wear resistance.• Robust seal profile for harshest operating conditions.• Insensitive to pressure peaks.• High extrusion resistance.• High temperature resistance in case of suitable compound selection.• Dimensions according to MIL-G-5514 / AS4716.Range of Application:Hydraulic actuators in aviation applications.Media:• Synthetic-based lubricants, e.g.MIL-PRF-23699• Ester-based lubricants, e.g. MIL-PRF-7808, Skydrol LD4 and Skydrol 500B• Synthetic hydrocarbon-based hydraulic fluids, e.g. MIL-PRF-83282 and MIL-PRF-87257• Mineral oil-based hydraulic fluids, e.g. MIL-H-5606
