## Summary description

Barrow compression fitting 13/10mm (wei) is a mechanical connector designed to join 13 mm outer-diameter tubing to 10 mm inner-diameter hoses or pipes. The fitting provides a secure, leak-resistant joint using a compression sleeve and nut, suitable for liquid cooling loops, custom PC watercooling, aquarium plumbing, and small fluid systems where converting between these tube sizes is required.

## Long description

Barrow compression fitting 13/10mm, wei is a mechanical adapter engineered to connect tubing with a 13 mm outer diameter to hoses or pipes having a 10 mm inner diameter. The fitting uses a compressive sleeve and nut system to produce a tight, leak-resistant joint suitable for small fluid systems. It is intended for applications where a reliable transition between these two tube sizes is required, including PC watercooling loops, aquarium plumbing, and compact liquid circuits.
Advantages
The compression design creates a secure seal without the need for adhesives or heat-based joining methods, reducing assembly time and allowing disassembly for maintenance. Its compact form factor conserves space in constrained installations and provides consistent mechanical grip on both rigid and flexible tubing. Made to meet common demands of hobbyist and light industrial fluid work, the fitting offers predictable performance for low- to moderate-pressure liquid systems.
Suitable for
 Custom PC liquid cooling loops where 13 mm OD tubing must be reduced to 10 mm ID hoses
 Aquarium plumbing and small pond circulation systems
 Prototype fluid circuits and laboratory setups with low-to-moderate pressure
 Homebrew or hobby projects involving different tube standards
Key specifications
 Connection type: compression fitting with sleeve and nut
 Tube compatibility: connects 13 mm outer-diameter tubing to 10 mm inner-diameter tubing/hose
 Material: corrosion-resistant metal finish (wei color)
 Seal method: mechanical compression providing a leak-resistant joint
 Application pressure: suitable for low to moderate liquid system pressures (typical hobby/PC cooling use)
 Installation: hand-tightenable nut with optional wrench for final seating
How to use
Ensure both tube ends are clean and cut square. Slide the compression nut and sleeve onto the 13 mm outer-diameter tube, then insert the tube fully into the fitting body until it bottoms out. For the 10 mm inner-diameter hose, push the hose end over the opposing fitting tail until seated. Tighten the compression nut evenly until a firm resistance is felt; use a wrench for a final quarter-turn if required. After assembly, inspect the joint for proper alignment and perform a leak test under normal operating conditions before prolonged use.
Usage recommendations
Use the fitting in systems that operate within the manufacturer's intended pressure and temperature ranges and avoid aggressive chemicals that may degrade the tubing or fitting materials. Periodically check connections for signs of wear, loosening, or leakage and re-tighten or replace components as necessary. For long-term installations, consider using clamp backup on flexible hoses where mechanical strain or vibration is present.
