Frequently Asked Questions – PTFE Thread Seal Tape
What is PTFE thread seal tape used for?
PTFE thread seal tape is used to create a leak‑tight seal on threaded pipe joints and fittings. It lubricates the threads, prevents seizing, and fills the gaps between male and female threads to prevent leakage of liquids and gases.
What is the temperature range of PTFE thread seal tape?
PTFE thread seal tape has a wide operating temperature range of -200°C to +260°C, making it suitable for both cryogenic and high‑temperature applications.
How many wraps of PTFE tape should I use?
For standard threads, 3–4 wraps are sufficient. For high‑pressure gas or chemical lines, use 5–6 wraps of high‑density tape. Always wrap in the direction of the threads.
Can PTFE thread seal tape be used on gas lines?
Yes, but it is recommended to use yellow or pink gas‑rated PTFE tape which is thicker and specifically designed for gas and LPG lines. We offer gas‑rated tape that meets industry standards.
What is the difference between standard and high‑density PTFE tape?
High‑density PTFE tape has a higher density (1.20 – 1.40 g/cm³) compared to standard tape (0.75 – 0.95 g/cm³). It provides better thread fill, higher pressure resistance, and is ideal for gas, hydraulic, and critical industrial applications.
