Diesel Injector Pipe Flare Nut Socket Wrench Set – 17mm & 19mm (2-Piece)
Tackle hard-to-reach diesel fuel line fittings with confidence.

Ideal for professional mechanics and DIY automotive enthusiasts working on diesel engines.
Key Features
- Slotted open-side design: The side slot allows the socket to slip over a pipe and seat squarely on the nut, making removal and installation fast and efficient even in confined spaces.
- Two sizes included: One 17mm and one 19mm flare nut socket — the most common sizes for diesel injector pipe fittings.
- Versatile application: Suitable for diesel injector pipes, injection pumps, elbow nuts, thermal sensors, thermal switches, and other fasteners located on bent or tight pipework.
- 12.5mm (½") drive connection: Fits standard ½-inch drive ratchets, extensions, and torque wrenches already in your toolbox.
- Durable metal construction: Made from sturdy metal for long-lasting performance under the demanding conditions of automotive work.
- Nut-friendly grip: Engineered to engage the nut cleanly, reducing the chance of rounding off or stripping fittings on delicate fuel lines.

Frequently Asked Questions
Q: What size drive does this diesel injector pipe wrench set use?
A: Both the 17mm and 19mm flare nut sockets feature a 12.5mm (½-inch) drive connection, making them compatible with any standard ½" ratchet handle, breaker bar, or torque wrench.
Q: Can these sockets be used on pipes other than diesel injector lines?
A: Yes! While they are specifically designed for diesel injector pipes and injection pump fittings, the slotted flare nut design also makes them suitable for elbow nuts, thermal sensors, thermal switches, and other fasteners found on bent or curved pipework throughout a vehicle's engine bay.
Q: Will this tool work without damaging the nut on my fuel line?
A: Absolutely. The hexagonal flare nut socket is engineered to engage all six sides of the nut evenly, distributing force uniformly and significantly reducing the risk of rounding or stripping the fitting compared to using an open-end spanner.
