Conector para tubo rígido 14 mm da OPTIMUS, níquel escovado — conector de compressão para tubos de refrigeração rígidos de PC

OPTIMUS Hardtube Fitting 14 mm in satin nickel is a compression-style connector engineered for rigid PC cooling tubing with a 14 mm inner diameter. Designed to join hard acrylic or PETG pipes to other fittings and components, this fitting provides a compact, mechanically secure interface for custom water-cooling loops. The satin nickel finish offers corrosion resistance and a neutral metallic appearance that integrates with a wide range of builds and components.

Advantages

The compression design creates a tight, leak-resistant seal without adhesives, and the fitting is compatible with standard 14 mm ID rigid tubing profiles. Its metal construction increases mechanical durability compared with some plastic connectors, while the satin nickel coating improves surface wear resistance and resists tarnishing. The compact form factor allows for close-routing inside cases and around blocks or radiators, helping to maintain clean loop layouts.

Suitable for

• Custom PC liquid cooling loops using 14 mm inner-diameter rigid acrylic or PETG tubing
• Connecting tubing to water blocks, radiators, reservoirs, and pumps
• Repairing or upgrading existing rigid tubing runs where a compression connector is required
• Compact or high-density builds that require low-profile fittings

Key specifications

• Compatible tube inner diameter: 14 mm
• Connector type: compression-style for rigid tubing
• Material: metal body with satin nickel finish
• Intended use: PC custom liquid cooling systems
• Form factor: low-profile, compact connector suitable for tight routing

How to use

Confirm the tubing inner diameter is 14 mm and prepare the rigid acrylic or PETG tube by cutting a square, burr-free end. Slide the tube into the fitting until it seats fully against the internal stop, then tighten the compression collar according to the manufacturer’s torque guidance to secure the seal. When installing in a loop, ensure mating components such as blocks, radiators, or adapters are clean and properly oriented to avoid strain on the joint. After assembly, pressure-test the loop and inspect joints for leaks before full operation.

Recommendations

Use compatible 14 mm rigid tubing and avoid overtightening the compression collar to prevent cracking or deformation of acrylic or PETG pipes. Perform a controlled leak test at low pressure and monitor the fitting during the first hours of operation. Regularly inspect fittings for signs of corrosion, mechanical stress, or loosening, especially after system transport or maintenance.
