Gasket Packing Q&A No. 10: Gasket Penetration Leakage Edition
What causes leaks when using gaskets? ~Permeation leak edition~
There are various factors that can cause leaks when using gaskets, but this time I will explain about permeation leaks. ◆ What is permeation leak? 〇 A phenomenon where the sealing material is permeated, causing the internal fluid to leak. ◆ Countermeasures 〇 Increase the density of the sealing material by compressing it with tightening force to fill the tiny gaps inside the sealing material. ◆ Requirements for sealing materials 〇 Density 〇 Resistance to permeation 〇 Applying rubber or resin-based paste materials to the inner diameter end face is also effective.
