Expanded PTFE Tape

High-density thread sealing tape for pipe fittings and valve stems

Custom Quote | MOQ: 1 Roll

Our expanded PTFE (ePTFE) tape is a high-density, easy-to-compress sealing material ideal for pipe threads, threaded connections, and valve stems. Unlike conventional PTFE tape, our expanded tape has a unique microporous structure that provides superior sealing performance with minimal material waste. It conforms perfectly to thread profiles, creating a reliable, leak-free seal even on rough or damaged threads.

How to Apply

1

Clean the Thread

Ensure the thread surface is clean and dry. Remove any old sealant, debris, or oil.

2

Start at the End

Place the tape at the first thread, ensuring it follows the thread direction (clockwise when looking at the end).

3

Wrap Evenly

Wrap 2-3 times for tapered threads, 4-5 times for parallel threads. Maintain tension for a snug fit.

4

Assemble

Screw the connection together firmly. Do not over-tighten. The tape will compress and form a tight seal.
