Flare Nut Wrench 6-Point (Model 1105M/A) is a precision-engineered tool designed for the safe tightening and loosening of flare nuts on hydraulic, pneumatic, and fuel lines. Forged by Hans Tools from premium Chrome Vanadium steel, this wrench features a reinforced 6-point opening that provides significantly more surface contact than a standard open-end wrench, making it essential for working with soft metals like copper, brass, and aluminum.

Feature
Flare Nut Wrench 6-Point is built to solve the most common challenges in fluid line maintenance:
High-Contact 6-Point Design: The deep-walled, 6-point hex profile grips all sides of the fastener. This prevents the “spreading” of the wrench jaws under high torque, ensuring that the corners of soft hydraulic nuts remain intact.
Reinforced Offset Head: The head is offset at a specific angle to provide hand clearance and a better “swing” in crowded engine bays or industrial manifolds where space is a premium.
Industrial Chrome Vanadium (Cr-V): Cold-forged and heat-treated to professional industrial standards, ensuring the tool remains rigid and does not flex when breaking loose seized or rusted line fittings.
B2B Procurement & Industrial Applications
The Flare Nut Wrench 6-Point 1105M/A is a strategic asset for:
Automotive Brake & Fuel Service: The only safe choice for removing stubborn brake bleeder valves and fuel line connectors without causing permanent damage.
HVAC & Refrigeration: Ideal for tightening compression fittings on copper line sets where a leak-proof seal is mandatory.
Industrial Fluid Power Maintenance: Servicing pneumatic control lines and hydraulic sensors in automated factory environments.
Frequently Asked Questions (B2B FAQ)
Why choose a 6-Point over a 12-Point Flare Nut Wrench? For soft metals, a 6-Point Flare Nut Wrench is superior because it maximizes surface area contact. A 12-point wrench is more likely to “bite” into the corners of a brass nut and round it off if the fitting is over-tightened.
What sizes are available in the 1105M/A series? We offer a full range of Metric and SAE sizes. Please refer to our technical chart below for the exact millimetric and imperial configurations available for bulk B2B procurement.
Is the finish resistant to brake fluid? Yes. The 1105M/A features a high-polish industrial chrome finish that is specifically designed to resist corrosion from aggressive chemicals like DOT 3/4 brake fluid and gasoline.
