The Gemels GNS series are flat-face quick couplings in carbon steel, engineered for liquid cooling systems in Data Center environments. The flat-face interface is specifically designed to prevent fluid leakage and air inclusion during connect/disconnect operations — a key requirement in sensitive data center cooling infrastructures where cleanliness and reliability are critical.

Available in two nominal diameters — DN10 and DN12.5 — with a maximum working pressure of PN20 (2 MPa), the GNS series offers multiple connection end options:

For DN10:

• SAE4 — 7/16-20 UNF (male and female)
• SAE6 — 9/16-18 UNF (male and female)
• SAE8 — 3/4-16 UNF (male and female)
• Hose Barb 3/8" (male and female)

For DN12.5:

• SAE8 — 3/4-16 UNF (male and female)
• SAE10 — 7/8-14 UNF (male and female)
• SAE12 — 1-1/16-12 UN (male and female)
• Hose Barb 1/2" (male and female)

Key features include:

• Material: Carbon steel
• Face type: Flat-face — near-zero fluid spillage on disconnect
• Size range: DN10 and DN12.5
• Max pressure: 2 MPa (PN20)
• Thread options: SAE UNF (multiple sizes) and Hose Barb
• Application: Data Center liquid cooling systems

Part of Gemels' complete Data Center cooling coupling range — alongside the stainless steel UQD, LQC, and NVQD series — the GNS is manufactured by Gemels SpA, Italy, with over 50 years of expertise in hydraulic components.
