yellow and white teflon tape

[Seamus J. Wilson]

Is there any significant difference between the two tapes? Seamus J. Wilson

Chemically and mechanically maybe, maybe not, depending on brand and SKU. In practical terms the yellow is intended for gas pipes, the white for drinking water.

The yellow is typically thicker (that's why it's gas-rated--more material in same/fewer wraps).

At least that's my story and I'm sticking to it...based on what old f--t plumber told me wunst upon a time...

Hi, And yellow ones cost more. Also there is pink ones.

Please find this in any ASTM or code book and tell me where to find it.

I have no idea. Just posting a link with reference. Up to the reader to judge it's worth. Just like anything, consider the source.

It MUST be true. I read it on the Internet! Red...
