Hydraulic Bonded Seals & O-Rings

Hydraulic Bonded Seals & O-Rings

Flowfit supplies a wide range of hydraulic bonded seals and O-rings for industrial, agricultural, construction, commercial and mobile hydraulic systems. These sealing components are designed to help create secure, leak-resistant connections across hydraulic fittings, adaptors, ports and components.

Also known as hydraulic sealing washers, bonded seal washers, Dowty seals or hydraulic O-ring seals, they are commonly used to help prevent fluid leaks and maintain reliable hydraulic system performance.

Reliable Hydraulic Sealing Components

A dependable seal is essential in any hydraulic system. Bonded seals and O-rings help seal threaded connections, fittings and ports, reducing the risk of oil leaks, pressure loss and contamination entering the system.

They are suitable for hydraulic systems used for lifting, tipping, steering, pressing, powering and controlling machinery across a wide range of applications.

Bonded Seals and O-Rings for Hydraulic Fittings

Hydraulic bonded seals are commonly used under bolt heads, plugs and threaded fittings to create a tight seal between mating surfaces. Hydraulic O-rings are used in a wide range of sealing applications, including adaptors, couplings, valves, cylinders and other hydraulic components.

• Bonded seals for hydraulic fittings, adaptors, plugs and ports
• O-rings for sealing valves, couplings, cylinders and components
• Helps reduce leaks, pressure loss and fluid contamination
• Suitable for servicing, repairs and new hydraulic installations
• Available in a range of sizes to suit different hydraulic applications

Common Applications

Hydraulic bonded seals and O-rings are used across many hydraulic systems where reliable sealing performance is required.

• Agricultural machinery: tractors, loaders, trailers, attachments and farm equipment.
• Construction and plant equipment: excavators, dumpers, loaders and lifting equipment.
• Industrial hydraulics: power packs, manifolds, presses, valves and test rigs.
• Mobile hydraulic systems: vehicle-mounted equipment, trailers and recovery vehicles.
• Hydraulic servicing: replacing worn seals during maintenance and repair work.

Built for Secure Hydraulic Sealing

Flowfit hydraulic bonded seals and O-rings are selected for reliable sealing performance in demanding working environments. When correctly selected and fitted, they help maintain hydraulic pressure, reduce leakage and support long-lasting system reliability.

Replacing worn or damaged seals can help prevent downtime, protect hydraulic components and keep your equipment operating efficiently.

Choosing the Right Hydraulic Seal

When selecting a hydraulic bonded seal or O-ring, it is important to check the size, material, sealing application, working pressure, temperature range and compatibility with the hydraulic fluid being used.

If you are replacing an existing seal, checking the current seal dimensions and application type is a good starting point. If you are unsure, our team can help you identify the correct bonded seal or O-ring for your hydraulic system.
