[iLLuSioN]

I just got in my PA120.3 and I was expecting no screws cause I bought 2 bitspower 90 degree 3/8 5/8 compression fittings...however they don't fit... what am I missing here those fittings weren't cheap which do I need?

I remember I had to order $30 fittings from Canada for my thermochill, that said I believe DD makes some that fit it now. These work much better than the ones I had originally ordered.

You probably need 90s but just throwing out other options.

Thermochill radiators use G3/8 fittings. Most normal fittings are G1/4. You either need to get special G3/8 fittings, or just get a converter that will convert from the larger G3/8 down to G1/4.
