## Summary description

Clarks copper brake oil seals for hydraulic brakes, 1 mm thickness, pack of 10. These flat copper washers function as sealing rings for hydraulic brake systems, preventing fluid leakage at banjo bolts and fittings.

## Long description

Clarks copper brake oil seals are flat sealing washers designed for use in hydraulic brake systems where a 1 mm copper washer is specified. Supplied as a pack of 10, these rings create a metal-to-metal seal at banjo bolts and fittings to reduce the risk of hydraulic fluid leaks. The copper construction conforms to typical requirements for crush and adaptability at threaded joints used in bicycle, motorcycle and light vehicle hydraulic disc brakes.
Advantages
These copper washers provide reliable sealing performance in hydraulic brake assemblies thanks to their uniform 1 mm thickness and ductile metal properties. The flat profile ensures consistent contact and controlled deformation when tightened, producing a secure hydraulic seal without adding bulk. Supplied in a pack of ten, they offer convenient quantity for routine maintenance and repairs.
Suitable for
Sealing banjo bolts on hydraulic disc brakes for bicycles
Sealing hydraulic fittings on motorcycles and scooters
Maintenance and repair of light vehicle hydraulic brake lines where 1 mm copper washers are required
Replacement of damaged or crushed copper brake washers during brake servicing
Key specifications
Material: copper
Thickness: 1 mm
Form: flat sealing washer
Pack quantity: 10 pieces
Intended use: hydraulic brake sealing at banjo bolts and fittings
How to use
Install a single copper washer between the banjo bolt head or fitting and the mating surface, ensuring proper alignment before tightening. Torque the banjo bolt to the manufacturer’s recommended specification to achieve the required crush and form the seal; avoid overtightening which can over-deform the washer and cause sealing issues. Replace washers whenever a fitting is disassembled or if the original washer shows signs of damage, corrosion or uneven deformation.
Usage recommendations
Use the Clarks 1 mm copper washers only where a 1 mm copper sealing washer is specified by the brake system manufacturer; check brake fluid compatibility and torque settings. Store spare washers in a dry environment to prevent surface corrosion and handle with clean tools to avoid contaminating brake fluid or brake pads.
