Diesel Injector Pipe Flare Nut Socket Wrench 17mm & 19mm Set
Diesel Injector Pipe Flare Nut Socket Wrench 17mm & 19mm Set
Work smarter on tight diesel fuel line jobs with this 2-piece Diesel Injector Pipe Flare Nut Socket Wrench Set. Sized at 17mm and 19mm, these hexagonal sleeve wrenches are purpose-built for accessing and turning flare nuts on bent or hard-to-reach fuel pipes — exactly where a standard socket or open-end spanner simply won't fit.
The slotted, open-side design lets you slide the socket over a pipe and onto the nut without having to thread it from the end, making removal and installation fast, clean, and damage-free. Whether you're working on diesel injector lines, injection pumps, thermal sensors, thermal switches, or elbow-style fittings, this set gives you the reach and grip you need.
Made in Mainland China.

Frequently Asked Questions
Q: What drive size is compatible with these diesel injector pipe flare nut sockets?
A: Both the 17mm and 19mm sockets feature a standard 12.5mm (1/2") drive connection, making them compatible with most ratchet handles, torque wrenches, and drive extensions found in a typical mechanic's toolkit.
Q: Why do I need a slotted flare nut socket instead of a regular socket for diesel injector pipes?
A: Diesel injector and fuel pipes are often bent at angles that block a standard socket from reaching the nut from the end. The slotted side opening on these wrenches allows you to slide the socket directly onto the nut from the side, giving you full hex engagement even in confined or curved areas — without damaging the pipe or the nut.
Q: Are these sockets suitable for both loosening and tightening injector pipe fittings?
A: Yes. The hexagonal design provides secure, full-contact grip on the nut, allowing you to both loosen and tighten diesel injector pipe fittings, injection pump connections, thermal sensors, and elbow fittings without rounding or stripping the fastener.
