Seal Inox, blind rivet nut, Tubtara

Seal Inox® is a thin topcoat applied to stainless steel Tubtara® blind rivet nuts, making it easier to assemble stainless steel threaded parts. It reduces friction and prevents gripping (galling) during assembly. A cost-saving solution that reduces assembly time.
Seal Inox® topcoat will also slow down contact corrosion and can protect against various chemicals

The non-reactive peripheral seal, made of flexible organic based material, is applied to the under head bearing surface of Tubtara® rivet nuts with a flat head. It ensures an IP 67 waterproof Tubtara® sheet assembly (guaranteed under Dejond test conditions). During installation of the Tubtara® blind nut, the material fills any gaps, forming a robust seal between mating surfaces. The seal is also resistant to many automotive oils, antifreeze and transmission fluids.
