Bending Jig Set for 12 mm and 1/2 in Rigid Tubing

This PrimoChill set provides three aluminium jigs for 45 90 and 180 degree bends in rigid tubing. Each jig accepts 12 mm or 1/2 inch outer-diameter tube up to 14 mm. Mounting holes let the tools be fixed to a bench for repeatable results. The kit covers PETG acrylic and copper tubing materials.

Who Benefits and Who Does Not

Builders planning custom hard-tube loops with consistent angles will find the fixed jigs fast and reliable. Users who need adjustable angles or very large-radius curves cannot achieve them with these preset forms. Anyone uncomfortable heating and forming rigid tube should practise on scrap before committing to a loop.

Deciding Specification — Supported Tube Diameters

The jigs work with 12 mm and 1/2 in outer-diameter rigid tubing up to 14 mm. If your tubing falls outside this range the tools will not fit and the bends will not be accurate. Check the tubing specification before purchase.

Questions about this item

Will the 1/2 in. OD and 12 mm OD jigs fit the PETG tubing I already own?

The set includes three jigs sized for 1/2 in. OD and 12 mm OD rigid tubing up to 14 mm, covering PETG, PMMA and copper.

How do I verify each bend is accurate after heating the tube?

Each jig is machined for 45, 90 or 180 degree angles; match the cooled tube against the corresponding groove to confirm the bend radius.

Does the package contain a heat source or only the three bending tools?

The box holds the 45, 90 and 180 degree bending tools with mounting holes; a heat gun or other tubing heater must be purchased separately.
