Yes, you can use the PL15 in competitive welding adapters with radial sealing up to 60 bar. The inner diameters of the adapters vary and sealing may not be satisfactory in these cases. In higher pressure ranges, sealing with an O-ring is not possible; the seal between housing and process connection is used (the sensors with measuring ranges up to 100 or 160 bar do not permit installation of an O-ring). This means that, in higher pressure ranges, the medium could enter the thread area and harden or cause cross-contamination. The same can happen if the adapter is too wide for the O-ring of the sensor.
