PlasCity manufactures the PVC Invisible Flange Joint, an extruded profile designed to conceal the flange connection between duct sections for a smooth, seamless appearance where visible joints aren’t acceptable.
What is an invisible flange joint
It is a concealed connector profile that hides the flange line between two duct sections, giving the ductwork a clean, uninterrupted surface instead of an exposed seam.
Commonly specified where ductwork is visible to occupants and appearance matters as much as function.
What to check before selecting one
- Clean, tight fit that fully hides the flange line with no visible gap
- Smooth surface finish with no flow marks or die lines
- Dimensional tolerance held consistently so the concealed joint stays flush along the full run
- Enough flexural strength to snap or fit into place without cracking during installation
- Colour match consistency if the ductwork is exposed and visible
- Supplier can produce the exact profile dimension needed for your duct edge, not a generic size
