Threaded Glass Connectors

Several manufacturers make threaded connectors in various sizes and designs. Some have internally threaded glass, with bushings to hold tubes or plugs which screw into the glass - commonly called Ace threads. Some are externally threaded, with threaded caps, both open and closed. These can all be used to make a tight connection to a straight tube, sealing with an o-ring, or used to provide an interface with other materials. We can also provide 1/4-28 male threads, which is a standard size for connecting to assorted small tubing and valves via plastic and Teflon fittings.
