Soft Tube XSPC 13/10mm EPDM 1m — flexible coolant tubing for water cooling

XSPC Soft Tube 13/10mm EPDM, length 1 m, is a flexible coolant tubing intended for PC water-cooling loops and other liquid transfer applications in cooling systems. The tube has an outer diameter of 13 mm and an inner diameter of 10 mm, and is manufactured from EPDM rubber. Its construction provides elasticity for tight routing and bending around fittings and connectors while offering chemical resistance appropriate for common coolant solutions.

Advantages

The EPDM material delivers good flexibility and resilience against repeated bending, making the tube suitable for compact builds and complex loop layouts. Chemical resistance of EPDM reduces degradation from typical coolant additives and helps maintain clear flow paths. The 13/10 mm diameter balance provides stable flow characteristics for many custom loops while remaining compatible with standard compression fittings and hose clamps designed for that size range.

Suitable for

• PC water-cooling loops in desktop and small form factor builds
• Custom liquid cooling systems and prototype setups
• Routing coolant around tight bends and compact enclosures
• Replacement or maintenance of existing tubing with matching dimensions

Key specifications

• Material: EPDM rubber
• Outer diameter: 13 mm
• Inner diameter: 10 mm
• Length: 1 meter
• Color: Black
• Designed for use with liquid coolants and water-based solutions

How to use

Measure the required length and cut the tubing cleanly with a sharp knife or tubing cutter to ensure square ends. Slide the tube over fittings or compression inserts until it seats fully; use compatible compression fittings or hose clamps sized for 13/10 mm tubing to secure connections. When routing, avoid kinking by maintaining smooth curves and use routing guides or clamps if necessary. Verify all connections and perform a leak test with the system pressurized or filled with coolant before powering pumps or electronics.

Recommendations

For prolonged service life, flush the loop before installation, use coolants recommended for EPDM compatibility, and inspect tubing periodically for softening, swelling, or discoloration. Replace tubing if any signs of mechanical wear or chemical degradation appear. Avoid prolonged exposure to oils, strong solvents, or temperatures outside the manufacturer's specified operating range for EPDM materials.
