## Long description

STANLEY ring flare nut wrench model 866861 is a 9 mm through-style (pierced) flare nut wrench featuring a combined 6- and 12-point head. Designed for use on flare nuts, fittings and similar fasteners, this tool provides secure engagement on nut profiles while allowing access to fittings on lines without removing tubing. The through-style construction enables the wrench to slide over protruding tubes or studs, making it suitable for hydraulic, automotive and plumbing work in confined spaces.
Advantages
The 6/12-point head offers versatility by providing strong contact on nut flats while allowing easier alignment with a 12-point entry. The through-style (pierced) body permits work on fittings when tubing or studs pass through the wrench, reducing the need to disassemble lines. Precision-machined jaws ensure a reliable grip on flare nut shapes to minimize rounding and slipping. Constructed to withstand typical service loads in maintenance and repair tasks.
Suitable for
Automotive brake and fuel line fittings
Hydraulic hose and tube fittings in machinery
Plumbing flare fittings and compressed gas lines
Maintenance and repair tasks in confined or tight spaces
Key specifications
Size: 9 mm
Head type: combined 6- and 12-point
Style: through-style / pierced (allows passage of tubing or studs)
Material and finish: hardened steel with service-appropriate finish
Intended use: flare nut and fitting engagement for hydraulic, automotive and plumbing applications
How to use
Select the 9 mm ring flare nut wrench and fit the head over the flare nut or fitting so the wrench fully engages the nut profile. Slide the wrench over any tube or stud passing through the tool until the head seats squarely on the nut flats. Apply steady torque using the wrench body, ensuring to maintain full contact to reduce risk of rounding. For tight spaces, position the wrench with careful hand control and use short, controlled turns rather than excessive force. Inspect the nut and wrench engagement periodically to confirm secure contact.
Usage recommendations
Use the STANLEY 9 mm ring flare nut wrench for applications where access is limited and tubing cannot be removed. Avoid applying impact or hammer force to the wrench, and combine with appropriate penetrating lubricant on corroded fittings. Store the wrench in a dry place and inspect before use for signs of wear or deformation.
