Mechanical Metal Sealing Washer Bonded Seals , Brass Flat Washer Iso Passed
Bonded Seals
The bonded seal is a metal washer with a vulcanized rubber insert for use in high pressure applications where other
means of sealing are unsuitable. Bonded seals are now available in self centralising form, which eliminates seal offset
and makes for easier installation.
Available in Imperial and Metric sizes and various metals and sealing materials to suit your application.
Available Materials: , NBR, Silicone, EPDM....other materials on request.
