Cooling silicon bending insert for PC hard tubing Barrow GJSGW-12, 12 mm, 10 cm, white

Barrow GJSGW-12 cooling silicon bending insert is designed for 12 mm hard tubing used in PC liquid cooling systems. The 10 cm white insert fits inside rigid acrylic or PETG tubes to enable smooth bends without kinking, simplify tube routing in compact cases and help maintain consistent coolant flow. It is intended for use in custom water-cooling loops where controlled tube curvature and reliable internal support are required.

Advantages

The silicon bending insert provides internal support that prevents hard tubes from collapsing or forming sharp kinks when bent, maintaining cross-sectional area and reducing flow restriction. Its flexible but shape-retaining material eases installation by guiding the tube into a smooth curve and reducing the need for repeated heat and shaping. The white finish offers a neutral visual appearance inside clear or colored tubing while resisting common coolant chemicals used in PC loops.

Suitable for

• 12 mm rigid hard tubing made of acrylic (PMMA) or PETG
• Custom PC water-cooling loops in compact or cramped cases
• Routes requiring tight or controlled bends without heat deformation
• Systems where maintaining consistent coolant flow is important

Key specifications

• Inner diameter compatibility: for 12 mm outer-diameter hard tubing
• Length: 10 cm
• Material: flexible silicone designed for coolant contact
• Color: white
• Function: internal bending support to prevent kinks and reduce flow restriction

How to use

Cut the hard tube to the required length and ensure the inside is clean and dry. Insert the silicon bending support into the tube so it runs along the bend section; align it to the area where curvature is needed. Heat the tube as appropriate for its material, shape it around the insert to the desired radius, and allow the tube to cool and set. After shaping, install the tube and fittings as usual, taking care that the insert does not protrude into connection points or interfere with sealing surfaces.

Recommendations

Use with tubing and coolants compatible with silicone; avoid excessive stretching of the insert beyond its intended length. When forming tight bends, apply heat evenly to the tube material and test fittings for proper sealing after installation. Replace the insert if it shows signs of degradation or if coolant contamination is suspected.
