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.

Together with our US partner Sherex Fastening Solutions, Jan Maeyens and Marc Drossaert represented Tubtara® blind rivet nuts at the National Industrial Fastener & Mill Supply Expo in Las Vegas.
