Sealing nut

Sealing nuts combine a fastening function with a sealing function.

In appearance it is practically the same as a traditional threaded nut. Sealing nuts are tightened with special nut wrenches.

Applications

Sealing nuts are used wherever maximum joint tightness is required: in utilities, as well as in machinery, shipbuilding, aviation and transport manufacturing. These nuts are especially in demand when installing pipeline systems.

Features

Like other types of fasteners, this type of nut is made from durable materials — mainly metals, and in some cases plastic.

For use in environments with high humidity and chemically active components, sealing nuts made entirely of stainless steel, or of high-carbon steel grades with a protective coating, or of polyamide are suitable.
