How Do You Seal Stainless Steel Pipe Threads?
Stainless steel pipe threads are protected by sealant in order to prevent leakage, contamination and weathering. Sealing stainless steel threads also provides lubrication for easy assembly of male and female end connections. Pipes can be sealed using TFE tape or an anaerobic pipe dope or sealant. TFE tape has proven to be the more popular selection due to its convenient, simple, mess-free application. Step 1 Select a TFE tape based on tape density and thickness, which determine its ability to seal. Tape with 3-4mm thickness and a density of 1g per CC is most often recommended. Step 2 Start with the first thread on the male pipe. Wrap the TFE tape clockwise, in the direction of the thread spiral. The tape should not overhang the first thread, or it could contaminate the system. Step 3 Draw the remaining end of the tape tightly around the threads; it should conform to the threaded surface. Step 4 Press the TFE tape firmly at the overlapping points. Secure the tape into the threads using
