Thermal Grizzly DeltaMate Extender - MF14 Black Die Thermal Grizzly DeltaMate Extender are high-quality extension fittings specifically designed for custom water cooling systems. Made from solid brass, an alloy of copper and zinc, these fittings are not only harder and more corrosion-resistant than pure copper but also anodically compatible with other metals in the cooling loop. The sealing rings (O-rings) are made of EPDM (ethylene propylene diene monomer rubber), a material known for its high elasticity as well as ozone and UV resistance. This ensures a permanently secure seal. The robust design of the DeltaMate Extenders allows for easy and secure installation using an 8 mm hex key. The DeltaMate Extender - MF14 features a G1/4-inch external thread and a G1/4-inch internal thread. It serves as an extension fitting to precisely increase the distance between components by 14 mm. The matte black chrome finish provides a high-quality look that is also easy to clean. Thanks to the uniform outer diameter of all DeltaMate fittings, the products can be seamlessly and aesthetically integrated into your water cooling system.
