Steel Metric Flareless Fitting, 15.00 mm L Series Union

For most high-pressure hydraulic work, 400 bar max operating pressure covers a lot of ground. The pressure rating across the L Series actually spans 160 to 630 bar depending on configuration, and the whole thing is built with a 4:1 safety factor baked in. Forged or drawn high-quality steel construction means it's not going to be the weak point in your system as long as you're staying within those numbers and your tube OD is 15mm.

For a 15 mm tube outer diameter, this union matches that size and it is part of the L Series metric flareless fittings.
