The 17mm Semi-Open Ratchet Combination Flare Nut Wrench by GTV is an essential tool for automotive technicians and DIY mechanics who frequently work with hydraulic lines, brake systems, and fuel pipes. Its primary benefit is the specialized ratcheting mechanism that allows for continuous turns without removing the wrench from the fitting, significantly reducing labor time in tight spaces. However, users should note that the semi-open design requires precise alignment with the fastener to avoid rounding, making it less suitable for applications requiring extreme high-torque leverage compared to a solid-ring wrench.

Yes, it is designed for 17mm hexagonal and dodecagonal fasteners, though it is specifically optimized for fluid line fittings.
This tool is designed for precision and access rather than high-torque breaking. Avoid using extension bars or excessive force that could damage the internal ratchet.
Keep the tool clean of dirt and metal shavings, and use light machine oil to keep the internal parts lubricated.
It refers to the distance across the flats of the nut the wrench is designed to fit.
It functions similarly but is specifically shaped to pass over lines and tubes that a standard closed box-end wrench cannot reach.
Clean the ratchet head with a degreaser spray, allow it to dry, and apply a light machine lubricant to the internal teeth.
Ensure the wrench is fully seated on the fastener. If the nut is already rounded, this wrench may not be able to grip it properly; use a dedicated flare nut extractor instead.
To use this tool effectively, ensure the fastener is free from heavy debris or thick rust before engagement. Slide the opening over the tubing until the wrench fully seats onto the 17mm nut faces. Always ensure the wrench is pushed fully against the shoulder of the fastener to maximize surface contact and prevent rounding.
