The RISK RL227 is a compact double-ended open-end wrench for hydraulic disc brake hose fittings. With 7mm and 8mm openings on one slim tool, it lets you loosen and tighten brake hose bolts and banjo fittings quickly — ideal for installing, removing or bleeding hydraulic brake lines on your bike.

Key Features

• Two sizes in one – 7mm and 8mm openings cover the most common hydraulic brake fitting sizes.
• Compact 80mm length – easily reaches tight spots around brake levers, calipers and handlebars.
• Precision-fit openings – grip the nut cleanly to help avoid rounding off bolt heads.
• Essential for brake service – perfect for hose installation, removal, and brake bleeding jobs.
• Lightweight & durable – steel construction with a slim profile, easy to carry in a tool roll.
• RISK brand – private-label authorization available (Model RL227).

Compatibility / What It Fits

• For hydraulic disc brake hose fittings with 7mm or 8mm heads — including banjo bolts and hose fittings.
• Commonly used on Shimano hydraulic disc brake systems (e.g., XT, Ultegra) and other systems with 7/8mm fittings.
• Fits MTB, road and gravel bike hydraulic disc brakes.

Notes & Cautions

• Check your fitting size first — confirm it is 7mm or 8mm before use.
• Use the correct opening for the nut; do not force the wrench onto rounded or oversized bolts.
• Apply reasonable torque only — avoid over-tightening brake fittings.
• Keep the tool dry after use to prevent rust (steel material).
• Dimensions and weight are hand-measured and may vary slightly; for reference only.
