Outlet: G1/2 RHak according to EN 560. Inlet pressure gauge: 0 - 400/300 bar. Outlet pressure gauge: 0 - 16/10 bar. Width x Height x Depth: 240 x 240 x 85 mm. Important note for 300 bar pressure reducers - please check your cylinder connection! Cylinder pressure regulators for 300 bar have a manual connection according to DIN 477 Part 5 and are NOT backward compatible. This means they do NOT fit cylinders with a maximum filling pressure of 200 bar! If necessary, see our following tutorial, 3: Difference between 200 bar and 300 bar pressure regulators.
