When used correctly—starting from the root of the thread and maintaining a steady tension—the specially formulated polytetrafluoroethylene (PTFE) expands to fill tiny gaps, creating a leak-proof connection between the male and female threads.
In high-purity gas systems, system failure is often due to contamination rather than leakage.
The design logic of UltraGas is:

Because gas systems cannot tolerate any failures. ForeverSeal® GasSafe is designed specifically for gas pipeline applications, not a modification of generic PTFE tape. From material density and thickness to color-coded compliance and controlled manufacturing, every design parameter revolves around one goal: achieving a long-lasting, easily inspectable gas seal.
