The Exergy Performance 1-018-132 is a rail end that goes from M18x1.5 to M14x1.5. It adapts an M18x1.5 rail connection so it can take M14x1.5 hardware. Exergy does not publish a vehicle list for it, so you match it by the threads on your rail and on whatever you are connecting to it.
Fitment
Exergy lists this part under its general fittings with no engine or model-year list. Match it by thread. The rail side is M18x1.5, an 18 mm thread with a 1.5 mm pitch, and the other side is M14x1.5, a 14 mm thread with the same 1.5 mm pitch. Exergy also makes a separate rail end to M14x1.5 built for the LB7 Duramax, so LB7 owners should call us before ordering this one. For anything else, send us your VIN and tell us which rail port you are working on.
Why this part
Rail ports and the lines or fittings you want to run do not always share a thread. When the rail side is M18x1.5 and the hardware you are connecting is M14x1.5, this rail end is the step between the two. It comes from Exergy, which builds the rails, pumps and relief valves on the high-pressure side of common-rail diesels, so the adapter on your rail is made by the same people who make rails.

Frequently asked questions
Will this fit my LB7 Duramax?
Exergy makes a separate rail end to M14x1.5 specifically for the LB7. Call us with your VIN before you order so we can make sure you get the right one.
What is the difference between this and the M18x1.5 rail plug?
The rail plug closes an M18x1.5 port. This rail end converts it to M14x1.5 so something can connect there. Pick the plug if the port is being shut off and the rail end if something is being plumbed in.
Can you install it?
Yes. We install everything we sell. If you are re-plumbing a rail, call the shop and we will go over the whole setup with you.
