New Tubtara watertight solution

Dejond  continues to expand its range of watertight rivet nuts and improve its offer of worry-free, zero risk assembly solutions.

Tubtara® rivet nut solution can be also offered for challenging applications requiring a leak-proof, as well as a flush installation. 

The new watertight series with Precote® 5 resin seal applied on the shank underneath the small reduced head has achieved satisfying test results. 
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 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, the compressed seal only slightly reduces the rivet nut’s grip range and ensures an IP 67 waterproof assembly.
