This yellow PTFE tape is a gas-rated thread sealant for plumbing and industrial use. It prevents leaks in gas, water, and chemical pipe connections, withstands high pressure and temperature, and is easy to apply without sticking or tearing.
Yellow PTFE tape is a specially formulated thread sealant widely used in gas, water, and industrial piping systems. Its distinct yellow color indicates that it meets standards for gas line applications, making it a trusted choice for sealing natural gas, propane, water, and HVAC connections. Suitable for both professional and DIY use, it ensures a durable, leak-resistant seal across a wide temperature range.

1.Clean threads–ensure they’re dry and free of oil
2.Wrap clockwise, starting at the first thread
3.Overlap each wrap by about half–3 to 4 layers usually works
4.Tighten fittings by hand–avoid over-tightening
5.Test for leaks before full use
Q: What’s the difference between yellow and white PTFE tape?
A: Yellow tape is rated for gas lines and made to stricter standards. White tape is generally for water and low-pressure uses.
Q: Can it handle high-pressure lines?
A: Yes–it holds up to 20 bar (around 300 PSI) when applied correctly.
Q: How many wraps do I need?
A: 3–4 layers is typical. For larger fittings, an extra wrap may help.
Q: Will it work on plastic threads?
A: Yes–it seals well on metal, PVC, and most plastics.
Pro tip: Always wrap in the direction of the threads (clockwise on standard fittings) so the tape doesn’t bunch up when you screw parts together. For gas lines, always perform a leak check before putting the system into service.
