EK-Pro Tubing 6/12mm Reinforced EPDM 1m - Black 3831109848357 EK-Pro Tubing 6/12mm Reinforced EPDM 1m - Black is a reinforced, high quality, industrial grade EPDM rubber tubing in a matte black color. This durable matte black tubing is designed to withstand harsh conditions for very long periods of time. It offers a truly exceptional lifespan as it can resist UV, ozone, and heat exposure for many years, while its thick rubber walls prevent the coolant from evaporating. This tubing can be used at ambient temperatures of up to +80°C (+176°F) and with coolant temperatures of up to +100°C (+212°F). It is perfect for applications that require maximum flexibility and high abrasion resistance. Unlike most PVC and PUR tubing, this high-quality EPDM rubber tubing from EK ensures long-lasting operation and doesn't suffer from a plasticizer leaching effect that can cause blockage (gunking) in your liquid cooling loop. It is guaranteed to be hassle-free even in the long run, which is something other PVC or PUR tubings cannot offer. Specifications: Material: EPDM Color: Black, not UV-reactive Outer diameter: 12mm Inner diameter: 6mm Operating ambient temperature range: up to 80°C
