I stopped at a friends today. He just put a junkyard 4.0 in his XJ and was hooking up his trans cooling lines. He added an aftermarket trans cooler and had to T the line. All new tubing and 3/8” brass Ts. One of the connections kept leaking. He went through several clamps, he bought 4 Ts online so we switched those out and hose once and still the leak persisted. I finally had him give me one of the Ts and I filled it with water and blocked the ends. Sure enough it started leaking in the middle with no pressure applied. I checked 2 others and the same thing. POS Chinese internet crap at a “Good price”. Only choices in town are Lowes and HD. HD is closer but did not carry them. On to Lowes and they had them. They were 2-3 times thicker and heavier than the Chinese crap. Put them on and no leak. Waisted 2 hrs with this. On the bright side the beer was cold I gained some more brass scrap for recycling.
In the pictures you can see that the machining is not complete.
