Bosch Professional 90-graden hoekbuistang, 420 mm (1 600 A02 W3V)

Bosch pipe wrench 1600A02W3V, 420 mm with a 90° gripping jaw position is a hand tool engineered for working on pipes and fittings in confined or angled locations. The 90° jaw orientation enables access to joints and fasteners that are difficult to reach with conventional straight wrenches. The tool combines a long handle for mechanical leverage with serrated gripping surfaces to secure round and profiled workpieces during tightening or loosening operations.

Advantages

The 420 mm length provides extended leverage while remaining compact enough for use in tighter spaces. The 90° jaw position improves accessibility on offset or angled pipe runs and around obstacles. Hardened, serrated jaws ensure a firm grip on metal and plastic pipes, reducing slippage and marring. The overall design balances reach, control and torque delivery for plumbing, HVAC and general maintenance tasks.

Suitable for

• Tightening and loosening threaded pipes and fittings in narrow or angled locations
• Plumbing installations and repairs in residential and commercial settings
• HVAC maintenance where access is limited by ducting or equipment
• General maintenance tasks requiring a secure grip on round or irregular-shaped components

Key specifications

• Total length: 420 mm
• Gripping jaw orientation: 90° relative to handle
• Jaw type: serrated/hardened gripping surfaces for pipe engagement
• Handle: long handle for increased leverage and manual torque
• Intended use: manual pipe wrench for tightening and loosening pipes and fittings

How to use

Select the correct position on the pipe or fitting so the serrated jaws engage securely. Place the 90° jaw against the workpiece and apply steady force on the handle to tighten or loosen the joint. For stubborn connections, use gradual, controlled pressure to avoid slipping; reposition the wrench if needed to achieve the best bite. Maintain a stable stance and keep hands clear of pinch points while operating the tool.

Recommendations

Inspect the jaws before each use and remove debris that could reduce grip. Use appropriate personal protective equipment such as gloves and eye protection when working with pressurized or hot pipes. Avoid using the wrench as a hammer or prying tool; if additional leverage is required, use methods recommended for hand tools rather than extending the handle.
