Many metal parts which are designed to be pressure-tight, leak in spite of correct design, alloy specifications, and proper production procedures. When this occurs, it costs you in both time and money, especially after machining work has been done.

Very often the cause of this leakages is porosity in the part itself. Frequently these otherwise good parts can be saved using the impregnation process. Pressure vacuum, steam, liquids and gasses can often find their way through the porous walls of castings, or through weldments and other porous areas of the part causing loss of effectiveness.

WESTERN SEALANT’S impregnation process:

• Saves you time
• Saves you money
• Saves leaking parts
• Reduces production rejects due to porosity
• Repairs porous castings, weldments, etc
• Helps solve fabrication problems

The impregnation process can effectively seal the pores of the part, saving you both the time and the money of having to reject an otherwise good part, or to make a replacement part. We can impregnate many types of parts large or small, before or after machining operations have been done. Our impregnates are invisible on the finished part and do not affect  the part’s dimensions in any way. Plating and paint processes are routinely done after our process without any adverse affects. It improves the surface’s finish in most cases.
