How do you install 90 degree Thermaltake adapters?

[Xennlos]

So... My first time water cooling my system and I want to install the 90 degree adapters... I just don't really know how? It's the G1/4 90 degree Pacific adapter!

Are you getting the "Rotary 90" or the plain 90.

1. The TT Rotary 90 degree you just install to the WC Block and turn to your desired position.

or

2. The fixed plain 90 degree is pure luck as to where the threading starts and LIMITS you to a set angle.
