The Gemels LQC (Large Quick Couplings) series are stainless steel quick couplings engineered for liquid cooling systems in Data Center environments. Purpose-built for larger-diameter circuits where high flow capacity and structural reliability are critical, the LQC complements the smaller UQD series to cover the full range of cooling infrastructure needs.

Available in DN25, with a maximum working pressure of PN20 (1.2 MPa), the LQC series offers a wide choice of connection end types to suit different installation standards:

• G 1 — BSP parallel thread (male and female)
• N 1 — metric parallel thread (male and female)
• SAE 16 — 1-5/16-12 UN thread (male and female)
• G 1M — BSP male stud end (male and female)
• SAE 16M — 1-5/16-12 UN male stud end (male and female)

All versions are available in both male and female halves, with a body outer diameter of 57.7 mm (male) and 51.7 mm (female), and an internal bore of 46 mm for high flow throughput.

Key features include:

• Material: Stainless steel for corrosion resistance and long service life
• Size: DN25
• Max pressure: 1.2 MPa (PN20)
• Thread options: G, N (metric), SAE 16 — flat-face and stud-end variants
• Application: Data Center liquid cooling systems
