Hose Barb Joints Being Replaced with GL-18

To provide a safer option for installing and removing tubing, we have started the process of converting our hose barbs to GL-18 threaded joints on all glassware that connects to tubing. A plastic glass hose barb is inserted inside a cap and the cap is screwed onto the GL-18 thread. Installing the tubing onto the plastic hose barb instead of onto the glass hose barb reduces the potential for injury and damage to the glassware.
