We have made consistency adjustments to the sealing ring of the pressure sensor. At present, the sealing part of the pressure sensor has been fully covered in the ED groove, using FKM/FPM fluororubber with more reliable comprehensive performance. The advantage is that it can be tightened directly and can be completely sealed without the need for winding tape, as long-term use of winding tape can cause leakage. Therefore, this is a good adjustment. The threads involved include G1/2, G1/4, M14 * 1.5, M20 * 1.5, and we also accept customized threads (with certain quantity requirements)
