Почему все ГЕРМЕТИЗИРУЮТ неправильно?

The video explains why some threads leak while others last decades, focusing on the role of thread sealants. It contrasts ancient linen tape, modern paste, FUM tape, thread sealant, and anaerobic sealant, describing their mechanisms and limitations. The narrator demonstrates the effectiveness of anaerobic sealant by testing it on small and large compressors, showing minimal leakage over time. The conclusion emphasizes that understanding the physics, materials, and friction is key to reliable thread sealing.
