Bending Cord for 10mm ID Rigid Tubing

The PrimoChill 9.5mm OD solid silicone cord is designed for DIY liquid-cooling builders who work with 10mm inner-diameter acrylic or PETG tubing. It sits inside the tube while heat is applied, preventing the walls from collapsing or forming cavities during complex bends. The tight fit is intentional and requires stretching plus lubrication before insertion.

Internal Support During Heat Bending

The cord acts as a temporary mandrel that frees the builder from kinks, flat spots and air pockets when shaping rigid runs. It demands patience and practice; the solid construction makes removal harder than hollow alternatives and it cannot be stretched as far. A 3-foot length is supplied for cutting to the required bend sections.

Upgrade from Hollow Inserts or No Insert

Builders moving up from tubed inserts or improvised tools gain tighter bend radii with less surface distortion on intricate loops. The trade-off is a more difficult extraction and limited stretch, so the jump is worth it only when the routing demands bends that would otherwise collapse the tube.

Questions about this item

How does the 10 mm inner diameter affect bending performance?

The cord is sized for 10 mm ID acrylic or PETG tube, giving a tight fit that prevents collapse and air pockets during heating.

Does the solid silicone cord generate heat or noise during extended bending sessions?

The cord is a passive silicone insert; it produces no heat or noise while the tubing is heated and bent.

What tubing must I already have to use this 9.5 mm OD bending cord?

You need 10 mm inner diameter acrylic or PETG rigid tubing; the cord is not compatible with other sizes or materials.
