Alphacool EPDM-letku 13/10 - musta 1 m (3,28ft) Retailbox 5100116

For water cooling loops that demand reliability without the fuss, this Alphacool EPDM tubing stands apart from typical clear PVC options. Its matte black, fully opaque wall blocks light entirely, preventing algae growth inside the loop and maintaining a clean, professional look. Unlike plasticizer-laden soft tubes, this EPDM rubber remains flexible for years without hardening, cracking, or leaching contaminants into your coolant. With a 13 mm outer and 10 mm inner diameter, it pairs perfectly with standard 13/10 compression fittings, making it a drop-in upgrade for custom loops, AIO expansions, or industrial cooling projects.

Highlights

• Genuine EPDM rubber: no plasticizers, no dye leaching, no clouding
• Opaque black finish blocks 100% of light to stop algae and biofilm
• Wide temperature range from -30 °C to 90 °C for extreme environments
• Pressure rated up to 6 bar (0.6 MPa) for high-flow, high-head systems
• Excellent kink resistance even in tight bends and short runs
• 1 meter retail box length – enough for CPU-only loops or GPU extensions

In daily use

Cut the tube cleanly with a sharp hose cutter, then warm the end slightly in hot water if needed for easier fitting. The 1.5 mm wall thickness gives a secure grip on compression fittings without excessive force. Because EPDM is inherently UV-resistant, you can route tubing near case windows or external radiators without degradation. The matte surface resists fingerprints and dust, keeping your build looking tidy. For maintenance, simply flush with distilled water – the tube will not release residues that clog micro-fins or cloud acrylic reservoirs.
