Description
If you’re running a mechanical temperature gauge in your engine bay, proper thread compatibility is non-negotiable—this adapter ensures a secure, leak-free connection between your gauge and coolant passage. The Allstar Performance adapter bridges the gap between 5/8-18 female fittings and 1/2 NPT male ports, eliminating the need for custom fabrication or workarounds. Black anodized aluminum construction resists corrosion and withstands sustained engine heat without compromise.
