The Peterson Fluid Systems -8AN internal-hex port plug closes unused AN ports on dry-sump oil pumps, tanks and associated accessories. The internal hex installation makes tightening and removal simple during routine servicing or rerouting of plumbing. Intended as a practical service item, it fits into Peterson’s race-oriented oiling component range to maintain clean, sealed fluid systems when ports are idle.
