PrimoChill RTP12-630 PETG tubing 1/2in OD 30in 6 pack

Ready-to-bend PETG tubing for custom loops

This six-pack supplies 30-inch lengths of 1/2-inch OD rigid PETG tube with a 3/8-inch inner diameter and 1/16-inch wall. The material is stronger than acrylic and bends with heat so you can create tight radii and clean straight runs without extra angled fittings. It targets enthusiasts and modders building transparent hard-line cooling systems who want vivid colour options and USA-made virgin PETG. The pack covers most single-loop builds but is not for builders who need longer continuous lengths or larger OD sizes.

Heat-bend installation

Cut each 30-inch stick to length, deburr the ends, then use a heat gun to form bends up to 90 degrees before pushing into 1/2-inch OD rigid compression fittings. The thicker wall resists kinking better than acrylic, yet overtightening fittings or bending cold tubing can still cause stress fractures. Coolant type, flow rate and additive chemistry may alter tube clarity over time, so flush thoroughly before final assembly. Installers without a heat gun or bending insert will struggle to achieve repeatable radii.

Verify fitting compatibility

Confirm every component in your loop uses 1/2-inch OD rigid fittings — barbed or push-fit parts for soft tube will not seal. Measure the total run distance between blocks, radiators and reservoir to ensure six 30-inch sticks provide enough straight sections plus bend allowances. The tubing is not for builders who need smaller 3/8-inch OD hard line or flexible soft tubing that installs without heat tools.
