Thermal Grizzly DeltaMate Quick Disconnect Female – M, Gloss Nickel

The DeltaMate fittings are water cooling hose connectors for the individual components of a custom water cooling system. Manufactured with the usual Thermal Grizzly quality, the fittings are machined from brass. Brass, as an alloy of copper and zinc, offers the advantage of being anodically compatible with other metals while being both harder and more corrosion-resistant than copper. The sealing rings (O-rings) are made from particularly elastic, ozone- and UV-resistant EPDM (ethylene-propylene-diene rubber). The robust design of the DeltaMate fittings allows assembly using 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 Disconnect (QDC) are drip-free quick couplings with integrated shut-off function and vacuum-assisted leak protection design. The internal geometry of the QDCs is optimised for high flow and minimises flow resistance. The DeltaMate Quick Disconnect Female - F fitting features a female QDC connection and a G1/4" internal thread. For one 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 glossy nickel plating.

Features

• Drip-free quick coupling
• Integrated shut-off function and vacuum-assisted leak protection design
• Locking mechanism that snaps in by pressing and releases by sliding
• Internal geometry optimised for high flow minimises 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 rapid swapping of components in a water cooling loop. They are especially helpful for content creators, as for example, when replacing 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 available with external (M) and internal (F) threads. Although QDCs offer several advantages such as time savings and additional options for integrating more radiators, they also have drawbacks. QDCs consist of several smaller parts that must be precisely manufactured and then assembled by hand, resulting in higher production costs compared to conventional fittings. Moreover, due to their function, a slight pressure drop can occur, restricting water flow more than normal fittings. Therefore, it is 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 direction 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 thread (F) should be used on both sides of the quick coupling connection so that standard fittings for the hoses can be mounted at the QDC ends. In the flow direction of the loop, the same plug (male) and socket (female) halves 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 fittings as well as four DeltaMate ST fittings (ST13 or ST16) are required.
