Thermal Grizzly DeltaMate Extender - MF7 Black Die Thermal Grizzly DeltaMate Extender are high-quality extension fittings specifically designed for use in custom water cooling loops. Made from solid brass, an alloy of copper and zinc, these fittings are not only more corrosion-resistant and harder than pure copper but also anodically compatible with all other metals in the loop. The O-rings are made from EPDM (ethylene propylene diene rubber), a particularly elastic and durable material that ensures a long-lasting and secure seal. The robust design of the DeltaMate fittings allows for easy installation with an 8 mm hex key. The DeltaMate Extender - MF7 in matte black features a G1/4-inch external thread and a G1/4-inch internal thread. As an extension fitting, it increases the distance between two components by 7 mm. The matte black chrome coating provides a high-quality finish that is also easy to clean. Thanks to the uniform outer diameter of all DeltaMate fittings, the products can be seamlessly integrated into your water cooling system. A special feature of this extender is its compatibility: it can be used with two DeltaMate 90° swivel fittings to create a double swivel connection with an offset of 28 mm.
