Adjustable wrench key for pipe wrenches Proline 15x17 mm (5364159)

Proline adjustable wrench key 15x17 mm is a compact hand tool designed for operation of pipe wrenches and plumbing fittings. The tool provides two fixed jaw sizes—15 mm and 17 mm—allowing direct engagement with nuts, coupling nuts and valve fittings commonly found in domestic and commercial plumbing systems. Its small size and straightforward design make it suitable for confined spaces and quick on-site adjustments without the need for larger spanners.

Advantages

The wrench key offers dual jaw sizes in a single, lightweight unit to reduce the number of tools required at a job. Its durable metal construction ensures reliable torque transfer when tightening or loosening threaded pipe connections. The compact profile improves access in tight areas around pipe runs, under sinks and behind radiators, and the hand-operated format gives fine control for sensitive fittings that require moderate torque.

Suitable for

• Tightening and loosening coupling nuts on plumbing pipes
• Adjusting valve fittings and shut-off valves
• Maintenance and repair of domestic and commercial water systems
• Use in confined spaces where larger wrenches will not fit

Key specifications

• Jaw sizes: 15 mm and 17 mm
• Hand-operated, non-powered tool
• Compact, low-profile design for limited-access use
• Material: hardened metal for torque and wear resistance
• Finish: corrosion-resistant surface treatment

How to use

Select the appropriate jaw size (15 mm or 17 mm) to match the nut or fitting. Place the jaw over the nut so it seats fully, apply steady hand pressure and turn clockwise to tighten or counterclockwise to loosen. Use controlled force to avoid over-torquing sensitive valves or fittings. For stubborn or corroded connections, apply penetrating lubricant and allow it to work before attempting to turn the fitting. Maintain a stable grip and work incrementally if space restricts full lever movement.

Usage recommendations

For routine plumbing work, keep the wrench key with other commonly used spanners and pipe tools. Inspect the tool before use for wear or deformation of the jaws. Use appropriate personal protective equipment, avoid excessive force that could damage fittings, and store the wrench key in a dry place to preserve the corrosion-resistant finish.
