The screw joint system up to 5 bar –
what you should know about.
This economic screw joint system was developed especially for tubing made of PTFE, PFA or FEP, but it can also be used with tubes made of glass or steel. Its function is based on compression rings which provide a pressure resistance of up to 5 bar at room temperature. All parts which are exposed to the medium are made of PTFE. Only the nut which is not in contact with the medium is made of glass-fibre reinforced PTFE for better stability. The fittings and nuts have metric threads.
All components of this system have a universal chemical resistance, since the product is only exposed to PTFE.
Assembly:
1. Push the nut on the tubing/tube
2. Push V-ring and then the tapered ring on the tubing/tube 3. Tighten the nut on the threaded neck – ready
