Threaded glass tubes are especially useful when a glass tube needs to be connected to another component using a threaded fitting, cap, connector, flange, sealing ring, or laboratory accessory.

Jinan JSV Industrial Co., Ltd. supplies borosilicate screw threaded glass tubes in different thread sizes and customized dimensions for laboratory, chemical, scientific, industrial, and OEM applications.

Common Thread Sizes

Threaded borosilicate glass tubes can be manufactured with different thread sizes.

Common GL thread specifications include:

Other thread sizes and customized thread designs are also available according to customer requirements.

GL14 Borosilicate Glass Tube

GL14 Glass Tube is a small-size threaded glass component suitable for compact laboratory and chemical equipment.

GL18 Borosilicate Glass Tube

GL18 Glass Tube is another small threaded glass size used in laboratory and equipment assemblies.

GL25 Borosilicate Glass Tube

GL25 Glass Tube provides a larger threaded connection than GL14 and GL18.

GL32 Borosilicate Glass Tube

GL32 Glass Tube is used for medium-sized threaded glass connections.

GL45 Borosilicate Glass Tube

GL45 is one of the most widely recognized GL thread sizes in laboratory glassware.

GL45 Borosilicate Glass Tubes are used in various laboratory and chemical applications.

GL60 Borosilicate Glass Tube

GL60 Glass Tube is a larger threaded glass connection used for equipment requiring a larger opening.

GL80 Borosilicate Glass Tube

GL80 Glass Tube is a larger GL threaded glass component for applications requiring a larger threaded connection.

GL100 Borosilicate Glass Tube

GL100 Glass Tube is also a larger GL threaded glass component for applications requiring a larger threaded connection.

Threaded Glass Tube for Laboratory Reactors

One of the important applications of threaded borosilicate glass tubes is laboratory reactor systems.

Threaded connections make it possible to integrate the glass tube with compatible caps, fittings, adapters, connectors, seals, sensors, gas lines, and other laboratory components.
