Clarks hydraulic hose insertion needle for HAYES 2.5 mm, pack of 10 (CLA-HFK-30)

Clarks hydraulic hose insertion needles are precision metal tools designed to assist with assembly and routing of hydraulic brake hoses with HAYES fittings. Each needle has a 2.5 mm diameter and the set contains ten identical needles intended for repeated use in workshop or field maintenance. These insertion needles help guide hose liners and ferrules into position quickly and accurately, reducing the risk of damage to hose ends and ensuring a smooth, consistent fit during brake line construction or repair.

Advantages

The needles are made from durable metal for reliable performance during repeated insertions and resist bending under typical assembly forces. Their 2.5 mm diameter matches common hydraulic hose liner sizes used with HAYES fittings to provide a secure fit while feeding components. Supplied as a pack of ten, the set supports multiple repair jobs and reduces downtime by providing spare tools when one becomes worn.

Suitable for

• Feeding hose liners and ferrules into hydraulic brake hoses with HAYES fittings
• Workshop assembly and calibration of bicycle hydraulic brake lines
• Routine maintenance and on-the-road repairs where quick hose reassembly is needed
• Mechanics and hobbyists working with compatible 2.5 mm brake hose components

Key specifications

• Needle material: metal (durable, reusable)
• Needle diameter: 2.5 mm
• Pack quantity: 10 needles
• Intended use: insertion tool for hydraulic brake hose liners and ferrules

How to use

Select a needle and insert it carefully into the hose liner or ferrule to provide a stiff guiding core. While holding the hose and fitting steady, slide the liner or ferrule along the needle and into the fitting until correctly seated. Withdraw the needle once components are aligned, then proceed with final assembly steps such as cutting to length, fitting olives or barb connectors, and bleeding the brake system as required by the brake manufacturer. Use steady, controlled pressure to avoid deforming the hose end.

Usage recommendations

Keep needles clean and free of debris; inspect before use for any bends or damage. Replace individual needles if they show signs of wear that could scratch or deform hose liners. Use appropriate protective gloves and eye protection when performing brake hose assembly, and follow the hydraulic brake manufacturer’s assembly and safety guidelines.
