Description

Crescent Metric Flare Nut Wrench Set (3-Piece)

The Crescent CFNWS1-05 is a 3-piece metric flare nut wrench set designed for working with tube fittings and hex nuts where increased fastener contact is required. Built from chrome vanadium steel with full-polish chrome surfaces, the set is designed for automotive technicians, hydraulic service professionals, plumbers, HVAC technicians, and industrial maintenance trades.

Best Used For

  • Automotive Brake & Fuel Lines: Service flare nuts and fittings on brake, fuel, transmission, and other vehicle fluid-line systems.
  • Hydraulic & Pneumatic Service: Engage tube fittings and softer hex nuts with greater contact than a conventional open-end wrench.
  • HVAC & Plumbing Maintenance: Install and remove metric flare fittings on tubing, valves, and mechanical equipment without completely disconnecting the line.

Key Performance & Safety Features

  • Hex-Shaped Flare Nut Heads: Provide increased points of contact around the fastener to help reduce damage compared with conventional open-end wrench designs.
  • Chrome Vanadium Steel: Durable chrome vanadium construction provides strength and long service life for professional fastening applications.
  • Full-Polish Chrome Finish: Bright polished chrome surface resists corrosion and wipes clean easily after automotive, hydraulic, and industrial service.
  • Double-Ended Design: Three wrenches provide six working ends to cover common metric flare-nut applications while minimizing the number of tools required.
  • Double-Sided Size Markings: Sizes are stamped on both sides of the wrench beam for faster identification from multiple working positions.
  • Professional Specifications: Designed to meet or exceed applicable ASME and ANSI specifications.
