The Peterson Fluid Systems -12AN port to -4AN nose fitting adapts a -12 port down to a -4AN outlet while retaining a radiused inlet to support flow. Precision-machined aircraft aluminum with an anodized finish maintains a large-bore approach where possible and provides a compact nose transition for tight plumbing. Use it to step down AN sizes cleanly in high-flow oil and fluid system assemblies.
