Thermal Grizzly's DeltaMate GPU Block Terminal (the Through Terminal) is an optional 4-port pass-through fitting for DeltaMate GPU water blocks, which come pre-installed with a Direct Terminal. It is not a standalone product and can only be used in combination with one of those blocks.

How it is built
DeltaMate GPU Block Terminals are massive, heavy parts at 270 grams. Each one is precision-machined from high-quality brass and subsequently nickel-plated. Brass is an alloy of copper and zinc. Thermal Grizzly says it offers the advantage of being anodically compatible with other metals while being harder and more corrosion-resistant than pure copper. The included sealing rings (O-rings) are made from EPDM (ethylene propylene diene monomer rubber), a material known for its exceptional elasticity as well as its resistance to ozone and UV radiation.
Ports
The terminal features two in/out ports per side: one inlet and one outlet on the top, and one of each on the bottom. That gives the loop inlets and outlets on both the top and bottom sides, each with G1/4-inch threading. The package includes two DeltaMate sealing plugs for the threads left unused, so a run in and a run out takes two compression fittings, such as the DeltaMate 16/10.
Fit and product-specific notes
Note: the terminal requires assembly, and it is recommended for experienced users! A compatibility list is available online. An up-to-date list of all compatible DeltaMate GPU water blocks can be found in the Downloads section on the product page for the Through Terminal in the Thermal Grizzly online shop. That page pairs the terminal with the DeltaMate GPU Block for the Astral GeForce RTX 5090. Check the list for your block before ordering.
