Tapered and parallel threads can be sealed permanently, such as on screws, studs, nuts, dowels, fittings, caps and ring nuts.

The treatment facilitates assembly, assures instant seal and also allows for easy disassembly.

We have carried out this treatment at our facilities since 1996, and considering demands by our automotive clients for quality, this year we have extended ISO 9001:2008 certification to this operation. The sealants we apply are Henkel 5061, more appropriate for water fittings, and 516, which is resistant to diesel and other fuels.
