Beta Tools Copper-Berillium (Cu-Be) Spark-Proof Tools are specifically designed for safe operations in environments subject to potential risk of explosion, in the presence of flammable liquids and gases, or for any applications that require using perfectly antimagnetic, corrosion-resistant tools.All tools are certified by the Federal Institute for Materials Research and Testing (BAM) under European Directive 99/92/EC.Warning! Risk of explosion in ACETYLENE environment. The mechanical characteristics of spark-proof tools differ from those of normal steel tools. They should be used with extreme caution, avoiding overloads..tg {border-collapse:collapse;border-spacing:0;}.tg td{font-family:Arial, sans-serif;font-size:14px;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}.tg th{font-family:Arial, sans-serif;font-size:14px;font-weight:normal;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:black;}.tg .tg-5ua9{font-weight:bold;text-align:left}.tg .tg-s268{text-align:left}.tg .tg-0lax{text-align:left;vertical-align:top} Beta Tools - Spark-Proof Safety Valve Wrench Range Product Code Part Number A A1 L Ø Weight mm mm mm mm g 009650830 965BA 30 30 44 200 13 280 009650832 965BA 32 32 50 300 15 540 009650835 965BA 35 35 47 250 13 364 009650840 965BA 40 40 50 300 14 470 009650845 965BA 45 45 58 350 15 610 009650848 965BA 48 48 62 375 15 660 009650850 965BA 50 50 67 400 15.5 705 009650855 965BA 55 55 73 450 16.5 960 009650860 965BA 60 60 79 500 17.5 1205 009650865 965BA 65 65 82 550 18 1370 009650870 965BA 70 70 85 600 18 1540
