FormulaMod OD16 Bending Kit

This FormulaMod kit equips builders to shape rigid tubing with a 16 mm outer diameter for custom liquid-cooling loops. It bundles 45°, 90° and 180° bending molds, a silicone insert with a 12 mm inner diameter, a dedicated cutter and a grinding tool. The set targets enthusiasts assembling hard-tube runs who want a single package for cutting, deburring and forming bends.

Heat-first workflow prevents mold damage

The instructions require heating the tubing before placing it into the chosen mold; the molds themselves must never be heated directly. Following this sequence lets the material conform to the mold radius without stressing the tooling, yielding repeatable bends during extended build sessions. Skipping the heating step or applying heat to the mold risks deformed tubing and damaged forms.

Cutter limited to softer tube materials

The supplied cutter handles common PETG and similar plastics but is explicitly not recommended for acrylic tubing because it may lack sufficient strength. Builders planning acrylic runs should source a heavier-duty cutter separately. The silicone insert slides inside the tube during bending to prevent collapse, and the grinder cleans cut ends for leak-free fitting seating.

Questions about this item

How much heat does the kit generate during a full day of bending 16 mm OD tubing?

The kit itself produces no heat; you supply an external heat source to soften the tube before placing it in the 45°, 90° or 180° molds.

What tube stock must I already have for the included cutter, molds and 12 mm ID silicone insert to work?

You need rigid tubing with a 16 mm outer diameter; the cutter is not recommended for acrylic tube.

Will the 12 mm ID silicone tube and grinding tool fit the 16 mm OD hard tube I plan to keep from my last build?

Yes, the silicone insert and grinder are sized for 16 mm OD tube, so they work with existing stock of that diameter.
