The block is constructed of high-purity copper that is nickel electroplated to prevent oxidation. A high-flow design is used to allow multiple blocks to run in series. Top and bottom ports can be used to configure parallel or serial designs in multi-block setups.

Specifications:
Block material: nickel electroplated high purity copper + high quality acrylic
