This \u003cstrong\u003eBrass Tee Fitting\u003c\/strong\u003e distributed by FleetPro Parts \u0026amp; Tires is the DEF coolant and sleeper heater tee for \u003cstrong\u003eEPA 2017 and later PACCAR MX-11 and MX-13\u003c\/strong\u003e engines, in the factory \u003cstrong\u003efemale M27x2.0 x 3\/8in bead x male M27x2.0\u003c\/strong\u003e arrangement. A cracked tee here drips coolant onto the frame and starves both the DEF coolant circuit and the sleeper heater that shares it - which on a winter night means a cold bunk and a fault code. 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\u003eOne Tee, Two Circuits: The PACCAR MX DEF Coolant Tee Advantage\u003c\/h2\u003e\n\n\u003cp\u003eThis is a \u003cstrong\u003ebrass\u003c\/strong\u003e tee with three different ends, and all three matter: a \u003cstrong\u003efemale M27x2.0\u003c\/strong\u003e port, a \u003cstrong\u003e3\/8in bead\u003c\/strong\u003e hose leg and a \u003cstrong\u003emale M27x2.0\u003c\/strong\u003e thread. That combination is what lets a single fitting pick up the DEF coolant line and the sleeper heater leg off the same junction with no adapters, on \u003cstrong\u003eEPA 2017 and later PACCAR MX-11 and MX-13\u003c\/strong\u003e engines in Kenworth and Peterbilt trucks.\u003c\/p\u003e\n\n\u003cp\u003eThe bead leg gives the hose clamp a shoulder to hold behind so the line stays put through heat cycles, and brass shrugs off coolant, road salt and the temperature swings that split cheaper bodies. Match the fitting to the engine emissions era before you order - this is the EPA 2017 and later arrangement.
