SCREW JOINTS / COMPONENTS WITH GL THREAD
BOLA GL Tube Fittings – what you should know about
A distribution system consists of tubes or tubing and connection pieces, so-called tube fittings. The BOLA GL-Fitting-System is a modular system which consists of tube fittings, screw-in fittings, different stopcocks and valves.
All fittings have GL threads so that they can be connected to hard-walled tubing (PTFE, PFA, FEP) or tubes (e.g. glass, metal, plastic) by means of BOLA Laboratory Screw Joints.
Together with these BOLA Laboratory Screw Joints (from page 88), the connection is absolutely tight and even suitable for vacuum; the screw joints for GL 14, GL 18 and GL 25 even resist pressures up to max. 10 bar at room temperature.
The system is completed by accessories like quick connectors, dirt traps and GL hose connectors.
BOLA PRACTICAL-TIP
Don’t fear blocked passage bores:
The special construction of our fittings does not allow tubing to be pushed in too far.
