We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
Typically used to connect two female-threaded components in low-pressure fluid, air, or water piping systems. In heavy-duty truck and trailer applications, these nipples can be found in air brake plumbing, small coolant lines, or general hardware assemblies. Replacement is necessary when threads become corroded, stripped, or the nipple develops leaks under pressure.
