Flexmaster Series Danfoss / Eaton Flexmaster Tube and Pipe Joints Gasket

For the bulged, straight-through joint style, they will handle up to 4 degrees of angular misalignment per end. If you are using tees, elbows, or crosses, the misalignment limit is up to 2 degrees per end.

The self-restrained style does grip the pipe or tube using a stainless steel ring inside the gasket, which keeps the joint from sliding along the pipe. That said, the joint itself is not built to hold the overall hydraulic lines system in place. You still need your normal hangers, guides, and anchors to keep the system from moving. The grip ring handles joint-level retention, not system-level restraint.
