Hydraulic/pneumatic systems: 
Used for sealing pistons or end caps of hydraulic cylinders, pneumatic cylinders subject to high pressure (e.g. construction machinery, injection moulding machines).
The square cross-section provides a more stable sealing performance and reduces the risk of extrusion deformation under high pressure.
Flange connections: 
Replace O-rings in flat seals on pipe flanges or equipment interfaces to prevent liquid or gas leakage (e.g. chemical pipelines).
