Bonded seals – flat seals made of metal and elastomer

 

HUFA is your competent partner for the development and manufacture of bonded seals according to customer-specific specifications or standards. 

We produce bonded seals in various customer-specific designs and combinations of materials, or in standard versions. The metal core can be provided with various types of surface protection as required.

A bonded seal is a combination of a metal flat ring and a vulcanised rubber sealing pad, which is used in places where it is not generally possible to achieve a high tightening torque or where loss protection in the form of a centring lip is desired.

This kind of metallic seal is predominantly used to seal flange or screw joints against excess pressure. The most frequent areas of application for these components include the automotive sector, as well as pneumatic systems, mechanical and plant engineering, pressure vessel construction and household technology.

Customer-specific solutions

In addition to the pure sealing function of a bonded seal, we provide our customers with specific solutions to make fitting easier and to increase product safety. Application-specific designs can, for example, prevent the absence or loss of seals during the fitting processes.
