PTFE thread seal tape is a heavy-duty, oxygen-safe sealant for sealing threaded pipe connections on water, gas, steam, and compressed air systems. The 19mm width and 0.1mm thickness provide excellent coverage and grip, with high-density PTFE that tears cleanly without stretching or requiring primer. Ideal for plumbers, gas fitters, electricians, and facilities managers who need reliable, chemical-resistant sealing for industrial and domestic installations.
