Norris produces a patented asbestos-free acetylene cylinder. Manufactured from steel disks that are cold cupped, drawn, and welded to form a shell, Norris acetylene cylinders meet DOT 8/TC 8WM or DOT 8AL/TC 8WAM specifications. Our Pacesetter asbestos free acetylene cylinders are filled with our patented,  highly porous lime-silica slurry (right), which provides the stabilization necessary for safe storage of acetylene gas. Fusible safety devices are also installed in each cylinder for added safety in the event of an external fire.
