Thermal Grizzly DeltaMate Compression Fitting, Brass - Gloss Nickel, for 14 mm Hard Tubes, G1/4 inch Thread

The Thermal Grizzly DeltaMate compression fitting stands apart from generic fittings by combining a robust brass core with a mirror-like gloss nickel finish, engineered specifically for 14 mm hard tubing in custom liquid cooling loops. Its knurled grip and multi-O-ring seal deliver a secure, tool-free installation that resists leaks even under pressure, making it a reliable choice for both first-time builders and experienced enthusiasts.

Highlights

• Precision-machined brass body with gloss nickel plating for corrosion resistance and a premium silver look.
• Optimized for 14 mm outer diameter hard tubes (PETG or acrylic) with a universal G1/4" thread.
• Multi-O-ring sealing system (EPDM) ensures a tight, leak-free connection without overtightening.
• Knurled grip allows easy hand-tightening, even in tight spaces.
• Reusable and durable, rated for typical PC cooling temperatures up to 60°C.

In daily use

Installing the DeltaMate is straightforward: slide the compression ring over your 14 mm tube, insert the tube into the fitting, and tighten the knurled collar by hand. The EPDM O-rings compress evenly around the tube, creating a secure seal that holds up to the vibrations and thermal cycling of a running system. The gloss nickel surface not only looks sleek but also wipes clean easily and resists tarnishing, keeping your loop looking sharp for years.
