Zoro Select Thread Sealant Tape

Zoro Select 21TF26 is a white PTFE tape designed for general-purpose thread sealing on pipe connections. It suits plumbers, maintenance technicians and DIY users who need a reliable seal on brass or steel fittings up to 3/4 inch diameter. The tape comes in a 43 ft roll with a 3/4 in width.

Temperature and pressure limits

The tape operates from -400 Degrees F to 550 Degrees F, covering extreme cold and high-heat systems. It withstands liquid pressures up to 10,000 psi and gas pressures up to 2,000 psi. Linear density ranges between 0.9 g/cc and 1.1 g/cc, ensuring consistent fill of thread gaps across that envelope.

Maximum thread diameter 3/4 in

This product is rated for threads no larger than 3/4 inch, so it will not suit larger pipe sizes or high-volume industrial mains. Buyers working on 1 inch or bigger connections must select a wider or heavier-grade sealant tape.

Questions about this item

Is the 3/4 inch width the right choice for my pipe threads?

The tape is 3/4 inch wide and rated for threads up to 3/4 inch diameter, making it a direct match for that size.

What does the 43 foot length mean for actual sealing jobs?

At 43 feet per roll you can wrap many standard pipe connections, each needing only a few turns of tape.

Does the 10,000 psi liquid rating guarantee a leak-free joint?

The 10,000 psi liquid and 2,000 psi gas ratings are maximum operating pressures; proper thread engagement and wrap technique are still required.
