Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It connects two female pipe-threaded ports of different sizes, commonly used in low-pressure air, fluid, or fuel lines on trucks and trailers. The hex center allows for easy tightening with a wrench. You would replace it if the old fitting is stripped, corroded, or leaking.
