ModMyMods MOD-0004 1/2" ID 3/4" OD PVC Tubing Clear diy cooling

Tubing for custom liquid cooling

ModMyMods MOD-0004 is flexible PVC tubing with a 1/2 inch inner diameter and 3/4 inch outer diameter, designed for DIY water-cooling loops. It suits builders assembling custom runs who want crystal-clear tubing that works with standard compression or barb fittings. The smooth inner walls reduce flow restriction, and the material is manufactured locally in western New York. Each quantity unit provides one continuous foot of tubing.

Fitting compatibility and bend radius

The tubing accepts both compression and barb fittings in the common 1/2 inch ID size, giving builders a choice of connection styles. Its flexible PVC construction allows routing around components, but tight bends can kink and restrict coolant flow, so gradual curves or angled adapters are recommended. The wall thickness is fixed by the 3/4 inch outer diameter, limiting how small a bend radius can be before the tube collapses. No special tools are required beyond a sharp cutter and fitting hardware.

Length options and loop coverage

Tubing is sold by the foot, with each unit delivering a single continuous length rather than separate short segments. A typical CPU-and-GPU loop often needs three to four feet, so multiple quantities are usually required for a full build. Ordering five units provides five continuous feet, avoiding joints that could leak. Very large loops or external radiator placements may exceed practical lengths for a single purchase, so plan the run before ordering.
