These remote radiator filler caps are perfect for water intercooler applications or other custom radiator installations.

Simple in design, the 3/4" barbed fittings are removable in case you need to install your own fittings in the 1/2" NPT Female threads.

The overflow tank nozzle is also removable in case you do not need an overflow tank. For water to air intercooler applications, it is common to either install a plug instead of the overflow tank nozzle or cap it.
