Frequently Asked Questions (FAQs)

What is this tape used for?

This PTFE tape is used to create leak-proof seals on threaded connections in plumbing, HVAC, industrial, and mechanical systems. It works on both metal and plastic threads.

Can I use this tape on potable water systems?

Yes. It is safe for potable water applications and meets industry certifications for clean, contaminant-free sealing.

What makes medium-density tape different from high-density tape?

Medium-density tape (3.5 mil) provides excellent sealing for general plumbing, water, gas, and chemical lines. High-density tape is thicker and used for more specialized applications such as stainless steel or heavy industrial systems.

Is this tape compatible with gas lines?

Yes, it is compatible with many gas applications. Always check local codes and certification requirements before using PTFE tape on fuel gas systems.

Will this tape shred or bunch when applied?

No. The medium-density formulation is designed to wrap smoothly and evenly without tearing, making installation fast and frustration-free.

Does PTFE tape prevent corrosion?

Yes. The tape is non-corrosive and prevents metal-to-metal contact, reducing the risk of galling, seizing, and thread damage over time.

Is it suitable for high-pressure systems?

Yes. When applied correctly, this tape performs reliably in many high-pressure water, hydraulic, and gas applications.

What temperature range does it handle?

It remains stable and effective from –310°F to 536°F (–190°C to 280°C), making it suitable for extreme-temperature environments.

How many wraps should I use?

Typically 3–6 wraps depending on thread size and material. Plastic threads may require slightly fewer wraps, while metal threads may require more.

Is UL or CSA certification important?

Yes. UL and CSA certifications confirm the tape meets tested performance standards for safety, reliability, and compatibility across plumbing and mechanical systems.
