There are three o-rings on the enhanced multi-link fittings 12mm adapter. https://www.overclock.net/content/type/61/id/2035606/width/500/height/1000/flags/LL

I assume the green o-ring is the regular g1/4 o-ring is this one  BP-WTP-O10-BK: https://shop.bitspower.com/index.php?route=product/product&search=o-ring%20&p=123&product_id=404

Is the internal o-ring replacement this one? BP-ML-O10-BK https://shop.bitspower.com/index.php?route=product/product&product_id=356
