The X-Ring Seal for Piston Head from FPS is a precision air-sealing upgrade designed for AEG gearbox piston heads. It replaces a standard O-ring with a specially shaped X-profile seal to improve compression efficiency and reduce wear during cycling.
Made from durable rubber, the X-Ring features a quadrilobed (X-shaped) cross-section that creates multiple sealing edges inside the cylinder. This design helps distribute pressure more evenly than a traditional O-ring, improving air seal consistency while reducing friction during movement. The result is smoother operation, more stable FPS output, and improved long-term sealing reliability.
Because of its lower friction characteristics, the X-Ring also helps reduce wear on both the piston head and cylinder wall. It performs especially well in setups where consistent sealing and efficiency are more important than maximum high-stress durability.
