PETG tubing inserts help to prevent deformity in tubing ends when using compression fittings with PETG tubing. When building a custom PC water cooling system with rigid tubing, PETG is often chosen over acrylic for its ease of use and lower cost. That ease of use comes in part from a lower melting point, which makes it easier to heat and bend. That same feature however can cause the tube to deform under pressure and heat, normally seen at the compression fittings. By supporting the internal diameter of the tube these tubing inserts prevent this warpage. TITAN RIG offers PETG tubing inserts in multiple sizes to provide you with the protection you need.
