Hi guys, so, i bought a thermaltake pr22-D5 plus pump, but i have a problem, it seems the threads are bad, i still have warranty ao i can send it, but the threads seem fine/not damaged, yet it wont fit my fittings nicely, i cant fully attach the fittings, the o-ring doesnt touch the base. I have tried monsoon fittings, and then i bought a g1/4 adapter from ek, 20mm, to see if it woukd fit better ,but it didnt really fit it well. I have not yet leak tested it. But i saw online that Bitspower sells a "npsm adapter", it seems english g1/4 is "npsm" and thats not the same as european g1/4?? i bought it from ScanUk, so it came from UK, do i need that bitspower adapter or just have a defective pump?? Thanks
