Thermal Grizzly DeltaMate Quick Disconnect Male - M, black

The DeltaMate fittings are water cooling hose connectors for the individual components of a custom water cooling system. Manufactured by machine from brass in the usual Thermal Grizzly quality, the fittings benefit from brass as an alloy of copper and zinc, which is anodically compatible with other metals and is both harder and more corrosion-resistant than copper.

The sealing rings (O-rings) are made from the particularly elastic as well as ozone- and UV-resistant EPDM (ethylene-propylene-diene rubber). The robust design of the DeltaMate fittings allows assembly with an 8 mm internal hex key. The uniform outer diameter of all DeltaMate connectors enables seamless integration of the individual products.

General Information
The DeltaMate Quick Disconnects (QDC) are drip-free quick couplings with integrated shut-off function and vacuum-assisted leak protection design. The internal geometry of the QDCs is optimized for high flow and minimizes flow resistance. The DeltaMate Quick Disconnect Female – F fitting features a female QDC connection and a G1/4″ internal thread. For a QDC coupling, one fitting with a male QDC connection and one fitting with a female QDC connection are required. For a premium finish, the fittings are coated with a matte black chrome plating.

Features
– Drip-free quick coupling
– Integrated shut-off function and vacuum-assisted leak protection design
– Locking mechanism for snapping in by pressing and releasing by sliding
– Internal geometry designed for high flow minimizes flow resistance while ensuring reliable sealing
– Precision-machined brass construction for durability and seamless integration

Why are QDCs special?
Quick couplings are special fittings that allow fast swapping of components in a water cooling loop. They are therefore particularly helpful for content creators, as, for example, when swapping a graphics card in a test setup with a custom loop, the entire loop does not need to be drained. Additionally, PC enthusiasts often use them to integrate external radiators into the loop. Each coupling consists of a plug half (male) and a socket half (female), both of which are available with external (M) and internal (F) threads.

Although QDCs, as mentioned above, offer several advantages such as time savings or additional possibilities for integrating more radiators, they also come with disadvantages. QDCs consist of several smaller components that must be precisely manufactured and then assembled by hand, leading to higher production costs compared to conventional fittings. Furthermore, due to their function, a slight pressure drop can occur, which restricts water flow more than normal fittings. It is therefore recommended to use only as many QDCs as actually needed.

QDCs and Water Blocks
For quick swapping of graphics cards in water-cooled test benches, we recommend forming directional pairs from a version with G1/4-inch external thread (M) and one with G1/4-inch internal thread (F). This prevents accidental reversal of flow direction and ensures that both valves retain the coolant when disconnected: on the water block side for the intake, a DeltaMate Quick Disconnect Female – M and on the hose side a DeltaMate Quick Disconnect Male – F. For the outtake, correspondingly on the water block side a DeltaMate Quick Disconnect Male – M and on the hose side a DeltaMate Quick Disconnect Female – F. For the hose-side QDCs, a DeltaMate ST fitting (ST13 or ST16) is also required to connect the hose.

QDCs for Connecting Hoses
If QDCs are to be used to connect two hoses, QDCs with internal threads (F) should be used on both sides of the quick coupling connection so that standard fittings for the hoses can be mounted on the QDC ends. In the flow direction of the loop, the same plug (male) and socket halves (female) of a QDC pair should be used on all QDC connections. For one QDC connection, two DeltaMate Quick Disconnect Male – F and DeltaMate Quick Disconnect Female – F as well as four DeltaMate ST fittings (ST13 or ST16) are required.
