Frequently Asked Questions
Can this be used on gas lines?
PTFE tape is commonly used on gas threaded connections. Use Gas Guard yellow tape where specifically required by local code.
How many wraps?
Typically 2–3 wraps on male threads in the direction of thread engagement.
What makes dense-grade better?
Dense-grade is thicker and provides a consistent seal without tearing — preferred over thin consumer tape.
