Peterson Fluid Systems Fitting R4 -20

What you get with this Peterson Fluid Systems R4 fitting is a single, well-made component designed for your custom fluid transfer setup. It's a -20 size fitting, meaning it's intended for a specific hose or adapter size within your system. This part is CNC machined from billet aluminum, which is a strong material that keeps the overall weight down. The anodized finish adds a layer of protection against corrosion and wear, helping it hold up over time in your engine bay or wherever you're routing your fluid lines.

The R4 design is notable for its shallow depth screw-in style. This feature is specifically included to help save weight in your build, which is often a key consideration when fabricating custom fluid systems. Whether you're working on a race car, a hot rod, or any project where you're routing fuel, oil, or coolant lines, this fitting offers a solid connection point.
