Hello Kevin,
Direct Connection means that it can connect OD12mm hard tube directly. When this fitting is combined with TA-GMALP2231-GB, they will be the G1/4" IG1/4" extender.
So your loop will be
Pump inlet > 90 Degree Fitting > 20mm M-M Extender >TA-GMALP2231-GB> TA- IGFALP2231-GB > 45 Degree Fitting > Compression Fitting.
20mm M-M Extender is the G1/4" IG1/4" extender too.
