The Peterson Fluid Systems 5/8-18 temp-port aluminum plug seals a tapped 5/8-18 temperature port while maintaining a clean appearance in oil tanks and plumbing. Sold as a threaded plug, the aluminum construction matches Peterson’s accessory hardware and keeps unused temp ports closed during service or when a sender is not installed. It’s a compact, service-friendly component for performance oiling systems.
