Remote Radiator Inline Filler Cap - 1.5"

****Free shipping to lower 48****

These remote radiator filler caps are perfect for custom radiator installations or just adding a better filler cap to your stock engine cooling system.

Simple in design, the 1.5" barbed fittings are removable in case you need to install your own fittings in the 1" 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 just leave it open since your system should not exceed the cap pressure.

As shown in the picture, the pressure rating on the cap is 0.9 bar (13 PSI).
