This 9/16" x 5/8" imperial flare nut spanner combines two commonly used sizes for compression nut applications, making it particularly valuable for technicians working on mid-range fuel injection systems and hydraulic installations. The dual sizing eliminates the need to carry multiple single-ended tools, improving efficiency when working on diesel injection pipes or refrigeration compression fittings. Manufactured from chrome vanadium steel that has been precision hardened and tempered, this spanner delivers the strength required for professional applications whilst the chrome plated finish ensures long-term corrosion resistance. The 15-degree jaw angle provides excellent access to compression nuts in confined engine bays or tight pipework installations, whilst the flare nut design maintains crucial contact area around five sides of the fastener to prevent rounding.
