Thermal Grizzly DeltaMate Compression Fitting, Brass - Gloss Nickel, ST16, 6-Pack

For PC builders assembling a hard-tube water cooling loop, the Thermal Grizzly DeltaMate Compression Fitting 6-pack offers a secure, leak-proof connection for 16 mm OD tubing. Each fitting is machined from brass with a gloss nickel finish, combining corrosion resistance with a clean, silver aesthetic that complements nickel-plated blocks and fittings.

Key specifications

• Type: Compression fitting for hard tube
• Compatible tubing outer diameter: 16 mm
• Thread: G1/4"
• Material: Brass with gloss nickel plating
• Seal material: EPDM O-rings
• Quantity: 6 fittings per pack
• Colour: Silver (gloss nickel)

Why choose it

The DeltaMate series is built for reliability. The brass body provides excellent structural integrity, while the nickel plating protects against corrosion in demanding coolant environments. The included EPDM O-rings ensure a tight seal, and the fittings are reusable, allowing for loop maintenance or reconfiguration without replacement. Hand-tightening is sufficient for a secure fit, simplifying installation.

Ideal use cases

• Custom water cooling loops with 16 mm hard tubing (PETG, acrylic, or glass)
• Builds using nickel-plated or silver-themed components
• Enthusiasts who need multiple fittings for a complete loop (CPU, GPU, radiators)
• Upgrades or maintenance of existing DeltaMate-equipped systems

Good to know

These fittings are compatible with all standard PC water cooling coolants, including distilled water with additives, premixed coolants, and ethylene glycol-based solutions. Always ensure tubing ends are cut squarely and deburred for a proper seal.
