Stopcocks, valve and keys - single way stopcock polished - without key
Ground glass stopcocks have a glass or PTFE plug with a hole or holes through it, allowing closure or opening with a half turn of the plug. Ground glass stopcocks require stopcock grease to lubricate and seal the plug and shell.
We offer sizes 12,5 mm, 14,5 mm and 18,8 mm. Glass or PTFE plugs. Many designs as straigt stopcocks, 2-way, 3-way, Y-bore and shapes with SJ or hose connections parts. For production we use Simax borosilicate glass tubes. We allways check glass quality, dimensions and optical clarity. All stopcocks are tested to be leaking free.
