40mm x 50mm x 8mm U-Cup Hydraulic Seal
Excellent service

Tried the local stores and couldn’t get the seals that I wanted. Most online retailers wanted to sell me hundreds of different sized seals - most would have ended up in the bin.

TotallySeals provided exactly what I needed, delivered quickly and communicated extremely well.

What are Bonded Seals?

Bonded Seals, also known as Dowty Seals, consist of a metal washer bonded to an inner rubber seal. This combination provides a durable, reliable seal that can withstand high pressures, making them ideal for sealing applications in hydraulic and pneumatic systems. Bonded Seals are often used in fittings, valves, and flanges.

How do Bonded Seals work?

Bonded Seals work by creating a tight, secure seal between two surfaces. When the assembly is tightened, the rubber element compresses and fills any gaps, forming a barrier that prevents fluid leaks. The metal washer provides structural support, while the rubber ensures flexibility, allowing for a robust seal even under high pressure.

What are the benefits of a Bonded Seal?

Bonded Seals offer excellent sealing performance in high-pressure applications, combining the strength of metal with the flexibility of rubber. Their design provides a secure, leak-free seal, reducing maintenance needs and improving the reliability of systems operating in demanding environments. They are also easy to install, making them a convenient choice for hydraulic and pneumatic applications.

How to choose the correct Bonded Seal?

When choosing a Bonded Seal, consider the diameter and thickness required for the application, as well as the type of fluid and pressure involved. Selecting the right material for the rubber element (such as Nitrile or Viton) is essential, as this will determine the seal’s compatibility with different fluids and operating temperatures.
