BOLA GL fittings are couplings made of PTFE with "GL" connecting thread. They are used to connect tubing made from PTFE, PFA, FEP and glass or metal tubes securely to each other. The fittings are resistant to almost all chemicals and temperature-resistant up to approx. +250°C. Operating pressures of up to 10 bar (at room temperature) can be withstood in combination with BOLA laboratory screw joints.
A major advantage is that you can connect hard tubes or pipes with a variety of outside diameters to one single basic part. For easy connection we recommend BOLA laboratory screw joints. These must be ordered separately according to the outside diameter of your chosen tubing.
