## Summary description

OPTIMUS hardtube fitting for 14 mm rigid tubing, single silver connector designed for PC water-cooling loops and custom coolant systems. Metal construction provides a sealed connection between hard tubing segments or between tubing and components. Suitable for durable joins in desktop liquid cooling, modding projects, and system maintenance where a 14 mm inner/outer compatible hardline is required.

## Long description

OPTIMUS hardtube fitting for 14 mm rigid tubing is a single metal connector in silver finish designed for desktop PC water-cooling loops and custom coolant systems. The fitting creates a sealed mechanical join between segments of hard tubing or between tubing and cooling components, offering a straightforward solution for building or repairing hardline coolant circuits that require a 14 mm compatible connection.
Advantages
The metal construction ensures mechanical strength and resistance to deformation under normal operating conditions, while the silver finish provides corrosion resistance and a neutral aesthetic that integrates with most builds. As a single-piece connector it simplifies routing and reduces the number of joints compared with more complex fittings, and it is compatible with rigid tubing systems that match the 14 mm dimensions.
Suitable for
 Custom PC water-cooling loops using 14 mm hard tubing
 Repairing or replacing a single segment in a hardline coolant system
 Modding projects that require metal, low-profile connectors
 Desktop systems where a sealed, durable join is needed between tubing and components
Key specifications
 Connector type: metal hardtube fitting for rigid tubing
 Compatible tubing size: 14 mm hard tubing
 Finish: silver
 Application: liquid cooling joins between tubing segments or tubing-to-component connections
 Material properties: metal construction for strength and durability
How to use
Prepare ends of 14 mm rigid tubing by cutting square and deburring to ensure a clean surface. Slide the tubing ends into the fitting until fully seated and verify alignment to avoid stress on the joint. If the cooling loop design requires additional sealing, use compatible O-rings or recommended sealing methods for the tubing system in use. After installation, fill and pressurize the loop following standard leak-testing procedures before full operation.
Usage recommendations
Use with properly sized 14 mm rigid tubing and follow manufacturer-recommended sealing and leak-test procedures. Avoid excessive mechanical force during installation to prevent damage to the tubing or fitting surfaces. Inspect joints periodically for signs of wear or corrosion and replace as needed to maintain system integrity.
