Need some tank fitting help

I just bought a Omega 18cu ft tank from AOA and I'd like to put 90 degree fitting where the hose connects to the tank. I need a male to female 1/8" BSPP 90 degree fitting that can handle the pressure we run. Not being an expert on all the fitting types and materials I want to make sure I get something that's appropriate. 

I found this, but it's a swivel and don't know the pressures it could handle.

Thanks for any advice
