Thermal Grizzly DeltaMate Compression Fitting, Brass - Gloss Nickel, HT14, 6-Pack

Compression fittings for hard tubing water cooling loops that lock 14 mm tubing into G1/4" ports with a secure, leak-proof grip. The DeltaMate HT14 six-pack outfits an entire loop with matching gloss nickel fittings that resist corrosion and stay reusable through multiple rebuilds.

Advantages

Each fitting is machined from solid brass and finished in gloss nickel, giving the loop a clean, uniform silver look that complements nickel-plated blocks and radiators. The compression collar tightens by hand or with a tool, compressing the O-ring against the tube for a reliable seal without cracking or deforming the tubing. EPDM O-rings maintain flexibility over time and tolerate the heat cycles common in high-performance systems. Because the fittings are reusable, they can be removed and reinstalled when upgrading components or re-routing tubing.

Suitable for

• Custom water cooling loops with 14 mm outer diameter hard tubing (PETG, acrylic, glass, or metal)
• Enthusiast builds using G1/4" threaded components such as radiators, CPU/GPU blocks, pump/reservoir combos, and distribution plates
• Users who want a consistent gloss nickel finish across all fittings in the loop
• Builders who frequently modify or maintain their loop and need reusable fittings

Recommendations

For a clean and reliable hard-line loop, pair these DeltaMate fittings with 14 mm OD tubing and G1/4" components. Hand-tighten until snug, then use a fitting tool for the final quarter turn to ensure a leak-free seal. Inspect O-rings before each installation and replace if worn. The six-pack provides enough fittings for a typical CPU-only loop with a radiator and pump/reservoir; add more packs for multi-block or dual-radiator configurations.
