Dejond NV has added a sealing solution to its watertight range of Tubtara® rivet nuts, the HDKX series with precote® 5 resin seal, for applications requiring a flush installation.
The new precote® 5 resin material is applied on the rivet nut body, underneath the small or countersunk head, and was created after customers looking for a leak proof rivet nut for flush installation approached Dejond to find a reliable watertight solution.
During installation of the rivet nut, excess resin material is scraped from the shank towards the head, forming a seal between the flush head and the parent material, into which the insert is riveted. The seal is only 0.25mm thick, applies well on stainless and zinc plated steel and offers a good thermal and chemical resistance, making it suitable for use with water and many automotive fluids. For semi-hex rivet nuts the advised hex hole radius needs to be observed, but if correctly installed in properly formed holes, this resin seal ensures an IP67 waterproof assembly.
With the popular HX and HDPX series, featuring an O-ring or Rimlex® seal, Dejond states that the Tubtara® has set the standard for watertight rivet nut assembly.
Dejond is an EN9100 certified Belgian manufacturer of Tubtara blind rivet nuts, with an expertise in cold forming stainless steel, and innovative bespoke rivet nuts, and serves the general, automotive and aviation industries worldwide through a network of expert fastener distributors.
