ColtexTM is Optinova’s high-performing joint sealant solution made of expanded PTFE.

ColtexTM offers the unique properties of PTFE in a soft and durable sealing product. ColtexTM is highly versatile, allowing it to conform to irregular sealing surfaces. It provides excellent sealing for flanges, pipes, containers and other surfaces in high pressure environments. ColtexTM is available as string or gasket tape, with or without adhesive.
