Pinion Right CSFG-PIN-BUNDLE-R Our Pinions are distribution plates made specifically with The Crow in mind as feathers to its wings. Therefore, they are available in mirrored designs for right and left placement. They are made of high quality acrylic with a special design language that fits perfectly with The Crow. With their large volume of 250 ml, they work very well as reservoirs even for larger systems. Pinion comes with CNC-milled aluminum spacers and each pinion has been leak tested with air before it is packed and leaves our workshop.
