One of APM Hexseal®'s earliest innovations was a self-sealing hexagonal nut, or Seelnut®.Seelnut®'s install just like conventional nuts, and are designed for use with ordinary screws, bolts and studs, making them a quick and easy sealing option for all sorts of applications, especially where there is a need to withstand high internal or external pressures.Our Seelnut®s are made from high quality rubber, molded into a specially shaped cavity in the nut itself. With threads molded directly into the rubber, these self-sealing nuts form a positive seal along the threaded section of the Seelnut®, as well as with the contact surface, removing the need for gaskets, sealing compounds or extra surface preparation. The single piece design makes for a more consistent and reliable seal, resulting in a significant savings of time and expense, and contributing to overall performance efficiency.APM Hexseal®'s Seelnut®s are also reusable, meaning that they can be easily removed and reapplied, reestablishing the same reliable seal when torqued.
