Not all sealing tapes are created equal. Every job calls for a different PTFE grade — and the color is the best telltale. Here's a quick breakdown of what each color is actually built for.
White — Standard Type
Used on water lines and general-purpose plumbing. The most common type you'll find.
Pink — Drinking Water Lines
Thicker than standard tape, and meets potable water standards.
Yellow — Gas Lines
Approved for propane, butane, and natural gas.
Green — Oxygen Systems
For oxygen systems, including medical oxygen. Oil-free, and certified for gas use.
Gray — Stainless Steel
Formulated for stainless steel fittings — anti-galling and anti-seize.
Blue — Heavy-Duty Sealing
Extra thick, built for commercial and industrial use.
