União de anel de aperto para tubos de cobre, Koolance NZL-CU06 – para tubos de diâmetro exterior 6 mm em G 1/4 polegadas BSPP, prateado

Koolance NZL-CU06 is a compression fitting engineered to join 6 mm outer-diameter copper tubing to components with a G 1/4" BSPP threaded port. Finished in silver, the fitting creates a sealed, mechanical connection that is suitable for closed-loop liquid-cooling systems and other fluid-transfer assemblies that use copper tubing. The design is intended to provide a compact interface between rigid copper lines and standard G 1/4" BSPP ports while minimising the risk of leaks when installed correctly.

Advantages

The compression fitting offers a robust metal construction and a silver finish for corrosion resistance and consistent appearance. It enables a sealed connection without soldering, facilitating installation and maintenance of liquid-cooling loops. The component is designed to work specifically with 6 mm outer-diameter copper tubing and G 1/4" BSPP ports, providing a precise mechanical fit and reducing the need for adaptors or additional sealants when used as intended.

Suitable for

• Joining 6 mm OD copper tubing to G 1/4" BSPP-threaded ports
• Closed-loop PC watercooling systems using copper lines
• Small-scale fluid transfer assemblies where a compact, leak-resistant metal fitting is required
• Laboratory or prototype rigs that employ copper tubing and BSPP connections

Key specifications

• Compatible tube outer diameter: 6 mm
• Thread connection: G 1/4" BSPP
• Material: metal compression fitting (silver finish)
• Connection type: compression-sealed mechanical joint for copper tubing
• Intended use: liquid-cooling and general fluid transfer involving copper tubes

How to use

Cut the copper tube squarely and deburr the inner and outer edges to ensure a smooth seating surface. Slide the compression nut and ferrule (if supplied with the fitting) onto the tube, insert the tube fully into the fitting body until it reaches the stop, then tighten the compression nut onto the G 1/4" BSPP port by hand and finish with a wrench to the manufacturer’s recommended torque or until a secure, leak-free connection is achieved. Verify the connection under system pressure and inspect for leaks before putting the assembly into regular service.

Recommendations

Use clean, properly sized 6 mm copper tubing and ensure all threads are free of debris. Do not overtighten beyond a firm wrench finish to avoid damaging the ferrule or threads. When integrating into liquid-cooling loops, perform a pressure or leak test with the loop filled and circulated for a period before resuming normal operation.
