  1. Watertight Rivet Nuts

    Leave a Comment

    In an earlier post we talked about how corrosion should be considered when choosing the type of rivet nut to use in your next project, and what types of sprays can help deter or limit the pace of red rust and white rust from occurring.

    Now water will certainly speed up the corrosion process, but that shouldn’t eliminate the use of rivet nuts in wet conditions, or conditions where a rivet nut will spend some of its life submerged in water or fluid.

    Our partner Tubtara® has a few different watertight and fluid proof rivet nuts that are designed with seals underneath the flange to keep water and fluids from leaking through the rivet nut. Tubtara’s Watertight HX series feature a O-ring seal mounted underneath the flange, and provides protection against moisture, oil, and dirt under high pressures. Despite the O-ring, it will deliver a metal to metal contact after installation.

    The Watertight (H)DPX Series is a rivet nut that has an applied sealant underneath the head. This non-reactive seal is resistant to many auto oils, antifreeze and other kinds of fluids with a higher viscosity. The seal in the (H)DPX Series can come in a variety of different seal material including NBR, Viton, silicone, epoxy based, acrylate and polyurethane resin.

    Any application where you wouldn’t want water or fluid to leak underneath or through the rivet nut should require a watertight rivet nut. Without using one of the seals, whether it’s an O-ring or sealant, it may not be completely watertight – especially as corrosion begins to develop.
