The Torque series from EK Water Blocks is characterized by its clear and timeless design, free of frills and logo branding. The Torque series is part of the EKWB Quantum series but is also compatible with other products from EK Water Blocks.

The EK-HDC Torque fitting is a compression fitting that is mounted as an attachment on a tube with a 12 mm outer diameter to connect the tube to a G1/4-inch port.

It is intended to be used with a solid tube made of acrylic, copper, brass, or stainless steel. When used with EK-HD tubes, it can serve as an alternative to the EK-FC terminal to connect multiple full-cover water blocks together.
