It is designed for securely connecting equipment and fittings with GL threads to hard-walled tubing or tubes made of glass, plastic, or metal. This joint features a black screw cap made of PPS, with inner components including a V-ring (PPS), a tapered ring, and a sealing ring (both PTFE), as well as an O-ring (FKM) for tubing diameters under 3 mm (not exposed to the medium). It offers excellent chemical resistance, with the medium being exposed only to PTFE. This screw joint is suitable for vacuum applications and can withstand temperatures ranging from -50°C to +250°C, with a pressure stability of up to 10 bar.
