Steel Metric Flareless Fitting, 8.00 mm L Series Tube Plug, M 14x1.5

For a good chunk of hydraulic applications, 250 bar gets the job done without issue. That said, this is an L Series fitting, and the broader L Series range can go higher depending on tube size and configuration. If your system runs closer to the upper pressure limits in your circuit, it's worth confirming your working pressure sits comfortably within that 250 bar rating with a reasonable safety margin. The series carries a 4:1 safety factor, so there's built-in headroom, but staying within rated limits is the right call regardless.

That pressure rating matches the maximum operating pressure listed, so it should be suitable for systems up to 250 bar. Just make sure your system doesn't exceed that.
