2-Piece Diesel Injector Pipe Flare Nut Socket Wrench Set – 17mm & 19mm

Tackle hard-to-reach fuel line fittings with confidence using this 2-piece Diesel Injector Pipe Flare Nut Socket Wrench Set. Designed specifically for diesel fuel systems, these slotted hex sockets make it easy to loosen or tighten flare nuts on bent or angled pipes — without rounding off the nut or damaging surrounding components. Whether you're working on injector lines, injection pumps, thermal sensors, or thermal switches, this set has you covered.

Made in Mainland China.

Key Features

Slotted Side Design: The open-side slot allows the socket to slide over bent or curved pipe runs, giving you access to fittings that a standard socket simply can't reach.
Two Essential Sizes: Includes one 17mm and one 19mm hex socket — the most common sizes for diesel injector pipe and fuel line nuts.
12.5mm (1/2") Drive Connection: Compatible with standard 1/2" drive ratchets, breaker bars, and torque wrenches for versatile use in the workshop or on-site.
Versatile Application: Suitable for injector pipes, injection pumps, elbow nuts, thermal sensors, and thermal switches — anywhere a straight socket can't engage cleanly.
Durable Metal Construction: Built from sturdy metal for long-lasting performance under the demands of automotive and diesel engine work.
Protect Your Fittings: The precisely machined hexagonal opening grips nuts firmly, reducing the risk of rounding or stripping during removal and installation.

Frequently Asked Questions

Q: What sizes are included in this diesel injector pipe socket wrench set?

A: The set includes two flare nut sockets — one 17mm and one 19mm — covering the most common diesel injector pipe and fuel line fitting sizes used in automotive and diesel engine applications.

Q: What drive size does this socket set use?

A: Both sockets feature a 12.5mm (1/2") drive connection, making them compatible with most standard 1/2" drive ratchets, torque wrenches, and breaker bars found in any workshop.

Q: Why do I need a slotted (flare nut) socket instead of a regular socket?

A: Standard sockets cannot slide over the pipe to engage the nut when a fuel line or injector pipe is in the way. The slotted side of these flare nut sockets allows you to slip the socket over the pipe and onto the fitting, providing a secure hex grip without damaging the nut or the pipe.

Q: Can this set be used for components other than diesel injectors?

A: Yes — these sockets are also suitable for thermal sensors, thermal switches, injection pumps, and any elbow nut or bolt in a tight or angled location where a standard socket cannot engage properly.
