Thermal Grizzly DeltaMate Compression Fitting, Brass - Gloss Nickel, ST13, 6-Pack

Compression fittings for hard tubing in PC liquid cooling loops deliver a secure, leak-proof connection with tool-free assembly. The DeltaMate ST13 series from Thermal Grizzly combines high-grade brass construction with a gloss nickel finish, ensuring both durability and a premium aesthetic for custom water-cooling builds.

Advantages

These fittings are precision-machined from solid brass and plated with gloss nickel, providing excellent corrosion resistance and a mirror-like shine that complements any high-end system. The compression mechanism grips 13 mm outer diameter hard tubing firmly, while the EPDM O-rings create a reliable seal that withstands the pressures and temperatures typical of PC cooling loops. Installation requires no special tools—simply slide the compression ring over the tube, insert the tube into the fitting, and tighten the collar by hand for a secure hold. The G1/4" thread is the universal standard for water-cooling components, ensuring compatibility with a vast range of radiators, blocks, pumps, and reservoirs.

• Custom liquid cooling loops using 13 mm OD hard tubing (PETG, acrylic, glass, or metal)
• Enthusiasts and system builders seeking a premium, durable fitting with a nickel finish
