ModMyMods Clear PVC Tubing for Custom Loops

This ModMyMods MOD-0003 tubing is flexible clear PVC with a 3/8 inch inner diameter and 5/8 inch outer diameter. It is made for builders assembling custom liquid-cooling loops who need reliable, locally produced tubing. The smooth inner walls promote unrestricted coolant flow. Each unit sold equals one continuous foot of tubing.

Sustained Flow and Durability in Custom Loops

The smooth bore reduces friction so coolant maintains steady velocity during long gaming or rendering sessions. Flexible PVC construction resists kinking when routed through tight bends around components. Material holds up to years of continuous circulation without cracking or clouding. Compression and barb fittings both seat securely for leak-free operation over extended periods.

Thermals Noise and Power Considerations

As a passive conduit the tubing adds no noise or power draw to the system. Clear finish lets users visually confirm coolant clarity and flow rate at a glance. Low permeability helps retain coolant volume so top-ups stay infrequent. Builders who need coloured or UV-reactive tubing should look elsewhere because this model is crystal clear only.

Questions about this item

Will the clear PVC tubing cloud or leach plasticisers after months of continuous pump operation?

The smooth-wall PVC is formulated to resist clouding and plasticiser leaching during long-term liquid-cooling use.

Which fittings must I already have to connect this 3/8" ID × 5/8" OD tubing?

You need compression or barb fittings sized for 3/8" inner diameter and 5/8" outer diameter.

Can I mix this tubing with older acrylic rigid runs in the same loop?

Yes — the flexible PVC joins compression or barb fittings that also accept rigid acrylic of the same 3/8" ID × 5/8" OD size.
