## Long description

Clarks hydraulic hose compression ferrules for Avid 5 mm — pack of 10 are metal fittings designed to create a secure, leak-resistant connection between 5 mm hydraulic brake hose and Avid-compatible fittings. These ferrules are intended for use during assembly or repair of bicycle hydraulic brake systems, providing the mechanical compression needed to hold the hose in place and form a reliable seal at the hose-to-fitting interface.
Advantages
These compression ferrules are manufactured to provide consistent compression and a tight fit on 5 mm hydraulic hose, reducing the risk of fluid leaks and improving connection stability. Supplied as a pack of 10, they enable multiple fittings or spare replacements during servicing. The ferrules' shape and dimensions match Avid-style fittings commonly found on many hydraulic brake systems, allowing straightforward installation with standard brake assembly procedures.
Suitable for
Assembling new hydraulic bicycle brake lines using 5 mm hose
Replacing worn or damaged ferrules on Avid-compatible fittings
Routine brake maintenance and emergency field repairs
Workshops and home mechanics servicing hydraulic brakes
Key specifications
Compatibility: Avid-style hydraulic brake fittings
Hose diameter: for 5 mm hydraulic hose
Material: metal compression ferrule (engineered for mechanical sealing)
Pack quantity: 10 ferrules
Application: hose-to-fitting compression for hydraulic brake systems
How to use
Slide a ferrule onto the cut end of the 5 mm hydraulic hose before inserting the hose into the Avid-compatible fitting. Ensure the hose end is cut square and free of burrs for a proper seal. Push the hose fully into the fitting until it seats correctly, then tighten the fitting according to the brake manufacturer's torque or tightening instructions so the ferrule is compressed and forms a seal. After assembly, bleed the brake system and check for leaks under pressure before regular use.
Usage recommendations
Use one ferrule per hose end and replace ferrules whenever removing hoses for service; always follow the hydraulic brake manufacturer's installation and bleeding procedures and use appropriate tools to avoid deforming the ferrule or hose.
