Bonded Seal (Dowty Seal) Manufacturer And Supplier

Bonded Seal (Dowty Seal) is a washer used to seal around a bolt or screw. These seals are available in metric and inch dimension. Bonded Seal (Dowty Seal) consist an outer annular ring of steel and an inner ring of elastomeric material. An inner ring of elastomeric material is known as a gasket. Dowty Seal acts as sealing discs which seal threads and flange joints. Bonded seals are high-pressure seal used in hydraulic, pneumatic, and mechanical sectors. The metal washer in bonded seal prevents over compression and limits deformation of the elastomeric ring (gasket).
At Concept Seals, we offer a comprehensive range of high-quality bonded seals designed to provide reliable sealing solutions for a variety of applications.Bonded seals, also known as Dowty seals or bonded washers, are sealing devices used to create a reliable and leak-tight seal in various applications. They consist of a metal washer with an elastomeric sealing ring bonded to it, forming a single integrated unit. Bonded seals are designed to provide effective sealing and prevent fluid leakage under high-pressure conditions.
  • Seal Integrity: Bonded seals offer excellent sealing performance, ensuring a tight and reliable seal between two mating surfaces. The elastomeric sealing ring is designed to deform and conform to the surface irregularities, creating a secure and leak-tight connection.
  • Pressure Resistance: Bonded seals are capable of withstanding high pressures, making them suitable for use in hydraulic systems, pipelines, and other applications with demanding pressure requirements. They help maintain system integrity and prevent fluid leakage.
  • Temperature and Chemical Resistance: Bonded seals are available in different elastomeric materials, such as NBR (nitrile rubber), EPDM (ethylene propylene diene monomer), and FKM (fluorocarbon rubber), each offering specific temperature and chemical resistance properties. This allows for compatibility with a wide range of fluids and operating conditions.
  • Easy Installation: Bonded seals are easy to install. They are typically placed between two mating surfaces, and upon tightening the fastener, the elastomeric ring compresses and creates a tight seal. This simplifies the installation process and reduces assembly time.
  • Vibration and Shock Absorption: The elastomeric material of the bonded seal provides vibration and shock absorption properties, helping to maintain seal integrity even in dynamic applications subjected to mechanical vibrations or impacts.
