-4 AN Fitting Aluminum Cap – Blue Anodized, GRE LIN-92904 – AN Fitting Dust Cap

Got some open -4 AN lines you need to cap off?

This little blue beauty from GRE is exactly what you need.

It's a machined aluminum cap with a slick blue anodized finish that'll look great on any fuel system or oil line.

Whether you're mocking up an engine bay, storing lines, or just need a clean finish, this cap screws right on.

It's brand new, part number LIN-92904, and comes with a warranty.

A small detail that makes a big difference in the looks department.

Oh, and quick heads-up for our California friends—Prop 65 warning applies, but that's pretty standard for metal parts these days.
