The LS rod seal is a rod sealing set featuring a Slipper Seal® design. It is designed for installation in market-specific grooves according to MIL-G-5514 / AS4716 and used in hydraulic and electromechanical actuators in aviation applications. It is particularly well-suited for high temperatures.
The LS rod seal consists of a PTFE rod sealing ring, a PTFE anti-extrusion ring and an elastomer O-ring as a preloading element. Due to its wide variety of material combinations, it is characterized by a diverse range of applications – particularly in use with aggressive media and in wide temperature fields, both in the low- and high-temperature ranges. The additional back-up ring at the back of the seal enhances extrusion resistance when pressure peaks occur and thus significantly increases the service life of the sealing system. The width of the back-up ring can be adjusted according to the groove so that in many cases there is no need for modification of an existing groove.
• Exceptionally high static and dynamic sealing performance.
• Good wear resistance.
• Minimal break-away and dynamic friction and no stick-slip tendency ensures uniform motion even at low speeds.
• Insensitive to pressure peaks.
• High extrusion resistance.
• Adaptable to nearly all media thanks to high chemical resistance of the sealing ring and large O-ring compound selection.
• High temperature resistance in case of suitable compound selection.
• Dimensions according to MIL-G-5514 / AS4716.
