New Tubtara watertight solution

Tubtara watertight

Tubtara has been continuously expanding the range of its watertight rivet nuts and improve the offer of worry-free, zero risk assembly solutions. New rivet nut solution for challenging applications requiring leak-proof as well as a flush installation have been developed. 

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.

With the existing popular range, Tubtara® has set the standard for watertight rivet nut assembly. The new watertight series with Precote® 5 further complements the range.
