Automatic core setting/Non-automatic core bonded washer
Bonded Seal Usage
Self-Centering Bonded Seals (Dowty Seals) are precision-engineered static sealing solutions designed for high-pressure fluid systems. Combining a metal washer and elastomeric sealing ring vulcanized into a single unit, they deliver superior performance in critical applications:

Bonded Seal Self-centering advantages
The location processing of sealing groove is not specially required. So it is ideal fittings for fast and automatic installation. Bonded Seal working temperature is -30 C to 100 C , working pressure is less than 39.2MPA .
Bonded Seal Material
1. Normal Material: Coppered Carbon Steel + NBR
2. Specially Required Material: Stainless Steel 316L + NBR , 316L+ FKM , 316L+EPDM , 316L+HNBR , Carbon Steel+ FKM and so on
Bonded Seal Sizes
Sealing discs to seal threads and flange joints. The discs consist of a metallic ring and a rubber sealing pad. Available in metric and imperial dimensions.
