This yellow PTFE thread sealant tape is formulated specifically for gas piping. The 43-foot roll suits residential and light-commercial installations where gas-rated sealing is required. It meets the POLY-TEMP GAS XHD series specification for fuel gas applications.

Linear density between 1.2 and 1.5 g/cc ensures consistent fill of thread roots under long-term vibration and thermal cycling.
