Diesel Injector Pipe Flare Nut Socket Set – 17mm & 19mm (2 Pcs)
Get the right grip on hard-to-reach fuel line fittings with this 2-piece Diesel Injector Pipe Flare Nut Socket Set. Designed specifically for diesel fuel systems, these hexagonal slotted sleeve wrenches make it easy to loosen or tighten injector pipe nuts on bent or awkwardly routed pipes — without damaging the fitting.
Key Features
- Slotted open-side design — slides over bent or curved fuel lines so you can reach nuts that a standard socket simply can't access
- Two sizes included — 17mm and 19mm to cover the most common diesel injector pipe and flare nut sizes
- 12.5mm (1/2") drive connection — fits standard ratchet handles and torque wrenches for controlled tightening
- Suitable for multiple applications — injector pipes, injection pump fittings, elbow nuts, thermal sensors, and thermal switches on top or side piping
- Durable metal construction — built to handle the torque demands of professional and DIY diesel engine work
- Silver finish — corrosion-resistant surface for long-lasting workshop use

Frequently Asked Questions
Q: What sizes are included in this diesel injector pipe socket set?
A: The set includes two flare nut sockets — one 17mm and one 19mm — covering the most commonly used diesel injector pipe and fuel line fitting sizes. Both feature a 12.5mm (1/2") drive for use with standard ratchet handles.
Q: Why do I need a slotted flare nut socket instead of a regular socket?
A: Standard sockets cannot slide over a bent or curved fuel line to reach the nut. The slotted open-side design of these sockets lets you position them directly onto the nut even when the pipe runs at an angle or through a tight space, allowing you to loosen or tighten fittings without damaging the pipe or the nut.
Q: Are these sockets compatible with a standard 1/2" ratchet handle?
A: Yes. Each socket features a 12.5mm drive connection, which is the metric equivalent of the standard 1/2" square drive, making them fully compatible with most ratchet handles, breaker bars, and torque wrenches found in any workshop.
