Sealing Washers for Leak-Free Fluid Systems
Ensure reliable, leak-free sealing in your brake, clutch, oil, fuel, and coolant systems with our range of sealing washers — essential for custom braided hose assemblies. Choose copper washers for high-pressure, high-temperature environments, Bonded Dowty Seals for reusable sealing in hydraulic applications, or Aluminium Crush Washers for lightweight, corrosion-resistant performance. Trusted in motorsport, road, and marine systems, these washers support a wide range of thread sizes and are the ideal match for our braided hose fittings, banjo bolts, and adapters.
-
What are washers used for in fluid and hydraulic systems?
Washers provide a secure seal between fittings, bolts, and surfaces, preventing leaks in hydraulic, fuel, and oil systems. They are commonly used to enhance the reliability and longevity of connections.
-
What is the difference between copper crush washers and aluminium crush washers?
- Copper washers are highly malleable, ensuring a strong seal by deforming under pressure. They are ideal for high-temperature and high-pressure applications.
- Aluminium crush washers are lightweight and corrosion-resistant, commonly used in motorsport and automotive applications where weight savings are a priority.
-
When should I use a bonded seal (Dowty washer)?
Bonded seals, also known as Dowty washers, combine a metal ring with a rubber sealing element. They are ideal for high-pressure hydraulic and fluid systems where a leak-proof seal is critical.
-
What are the advantages of using a crush washer?
Crush washers create a one-time-use seal by deforming under pressure. They offer:
- High-pressure and temperature resistance.
- Reliable, leak-proof connections.
- Compatibility with various fluids, including oil, fuel, and hydraulic systems.
-
How do bonded seals compare to crush washers?
Bonded seals offer a reusable sealing solution with a rubber element that maintains flexibility, whereas crush washers are designed for single-use applications that create a permanent seal.
-
Are bonded seals reusable?
Bonded seals can be reused if the rubber element remains undamaged and retains its elasticity. However, for critical applications, it is recommended to use a new washer to ensure a perfect seal.
-
How do I choose the right washer material for my application?
The choice depends on factors such as pressure, temperature, and fluid compatibility:
- Copper crush washers – Excellent for high-temperature and high-pressure environments.
- Aluminium crush washers – Lightweight and corrosion-resistant, ideal for motorsport and automotive applications.
- Bonded seals – Preferred for hydraulic systems requiring a reusable and high-pressure seal.
-
How do I install a crush washer correctly?
To ensure a proper seal:
- Place the crush washer between the fitting and the mating surface.
- Tighten the fitting to the manufacturer's torque specification.
- Do not reuse crush washers, as they deform upon installation.
-
How do I prevent leaks when using washers?
To ensure a leak-free connection:
- Choose the correct washer type and material for your system.
- Ensure all surfaces are clean and free from debris before installation.
- Tighten fittings to the specified torque to prevent under or over-tightening.
