It is a brass air fitting that takes a \u003cstrong\u003emale M12x1.5 thread with an O-ring\u003c\/strong\u003e on one end and gives you a \u003cstrong\u003e1\/4 in female NPT\u003c\/strong\u003e on the other, which is exactly what you need when a metric valve body, sensor boss or air dryer port has to feed a standard NPT gauge, hose end or accessory line. Trying to force an NPT fitting into a metric port is how ports get ruined. Manufactured by Automann to Fleet Standard specifications, we stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.\u003c\/p\u003e\n\n\u003ch2\u003eMetric Port, NPT Accessory: The M12x1.5 Adapter Advantage\u003c\/h2\u003e\n\n\u003cp\u003eThe important detail on this adapter is the \u003cstrong\u003eO-ring on the male thread\u003c\/strong\u003e. A metric straight thread does not seal on the threads the way a tapered NPT thread does - it seals on the O-ring face at the bottom of the boss. That means you tighten it down to seat the seal and stop, with no sealant tape, no pipe dope and no guessing at how many turns past finger tight. It also means the joint can be taken apart and put back together without the slow, one-way tightening that eventually splits a cast metric boss.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003e1\/4 in female NPT\u003c\/strong\u003e end is ordinary tapered pipe thread, so anything in the shop drawer threads straight in with tape or dope as usual. The \u003cstrong\u003ebrass\u003c\/strong\u003e body handles the moisture, road salt and compressor oil that live inside a heavy-duty air system and will not gall or seize into a valve body the way a steel fitting can. At FleetPro Parts \u0026amp; Tires, we know an air system is only as good as its weakest joint.
