Theres no CLEAR documentation about what an fittings are on this thing. The side port is 8an and the bottom is m22x1.5 orb to 8an that is basically just grey siliconed with no o-ring. Consider this when you buy. It looks and feels solid, and happens to fit almost perfectly in an $11 2lb fire extinguisher bracket if installed upside down. The overflow is a 1/8 npt as well. Going to use this for a GM LS degas tank. If you do, make sure to install a 0 psi radiator cap on your radiator (or remove just the little round recovery valve disc) and plumb the steam port and radiator overflow to the side port of this tank. The bottom port will tee into the front 3/4” heater hose. It will make filling it 1000x easier and there's NO bleeding procedure needed if you install it like this. Use a standard 16psi cap on this tank and run a small piece of hose from overflow to ubder the car. It will keep the engine cool, and make your heater blow fire when it gets cold outside again. :)

Very high quality reservoir, & what they need to include in the listing is that the bottom fitting is an M24x1.5 thread. The reservoir is exactly as expected, but if I were to be picky a smaller rad cap neck would have been preferred (it is a full size type-A neck), and I wish the side fitting was threaded like the bottom so I could replace the 8an flare with another size. (I had to use an adapter for a 10an connection) As-is it’s still worth a 5-star rating!
