Barrow Silicon Bending Insert for 10 mm HardTubes, 10 cm, white (GJSGW-10)

Barrow Silicon Bending Insert for 10 mm HardTubes, 10 cm, white is a flexible silicone mandrel designed to be inserted into 10 mm rigid hard tubing (PC/PMMA/ACRYL) to support controlled bending. The 10 cm length provides internal reinforcement along the bend zone, reducing the risk of kinks and fractures while preserving internal diameter and flow. The white silicone surface cushions the pipe wall during forming and helps produce smooth, consistent curves for custom water-cooling loops and precise hardline routing.

Advantages

The silicone insert protects the inner surface of rigid tubing during heat forming and bending, preventing collapse and micro-fractures that could disrupt coolant flow. Its size matches standard 10 mm hard tubes, ensuring a snug fit and even support along the bend. The flexible material allows repeated use and simple removal after shaping, while the neutral white finish is unobtrusive inside translucent or opaque pipes.

Suitable for

• Shaping 10 mm rigid PC, PMMA or acrylic hardline tubing for custom water-cooling loops
• Creating controlled bends without reducing internal flow or causing kinks
• System builds that require precise tube routing and neat hardline aesthetics

Key specifications

• Material: silicone insert for internal tube support
• Intended internal tube diameter: 10 mm hard tubing
• Length: 10 cm usable insert length
• Color: white
• Compatibility: designed for rigid PC/PMMA/ACRYL hard tubes

How to use

Insert the silicone mandrel fully into the 10 mm hard tube so the area to be bent is reinforced along the insert length. Apply controlled heating to the external tube following the tube manufacturer's guidelines until the material reaches forming temperature, then bend the tube gently to the desired angle while the insert supports the inner wall. Allow the tube to cool fully to regain rigidity before removing the silicone insert. Remove the insert by sliding it out carefully to avoid scratching the inner surface.

Recommendations

Use with appropriate heat sources and protective equipment; avoid overheating the tube to prevent deformation beyond the insert’s support range. Verify compatibility with the specific hard tubing material (PC, PMMA, ACRYL) and work in a clean environment to prevent debris from entering the coolant path. After shaping, inspect the inner surface for uniform curvature and ensure seals and fittings seat correctly before filling the loop.
