Flo Supply designed these double-ended AN wrenches specifically to fit B-nuts and sockets on hose end assemblies. Each wrench features two distinct ends, each tailored for different components of the assembly. The “B” side is designed for B-nuts, the fittings on tubing or hoses that secure the connections. This side of the wrench is precisely sized to ensure a secure and tight fit, preventing any potential damage to the fittings during installation or maintenance.

The opposite end, known as the “S” side, is intended for hose end sockets. These are the parts of the hose assembly where the hose connects to the fittings. The “S” side is precision machined to fit these sockets perfectly, allowing for easy and safe tightening or loosening. By using the correct side of the wrench for each component, users can achieve proper installation and maintenance of AN fittings, effectively preventing leaks and ensuring the durability of the connections.

The Flo Supply billet AN wrench set includes a comprehensive range of sizes. Each end of the wrench is engraved for quick size referencing, making them a versatile and essential addition to any toolbox. It must be noted that the Flo Supply double-head AN wrench set does not fit 3AN B-nuts.
