Unasco copper-filled PTFE anti-seize tape, 12mm x 15m
Available
Unasco Copper Anti-Seize Tape is a copper-filled PTFE tape that helps prevent galling during assembly and disassembly of components. Wrapped around a thread, it seals it against corrosive substances, dirt and grit. It is supplied in 12mm and 19mm widths, each 15m long. It is not recommended for stainless steel, and Unasco nickel and ceramic anti-seize tapes are made for that job.
Where this product is used
- General purpose anti-seize on threaded components
- Assembly and disassembly of threaded components
- Copper pipe threads
Features
- Copper-filled PTFE tape
- Thermally stable from -268°C to +260°C, the PTFE decomposes slowly up to +400°C and the remaining copper powder helps disassembly
- Not recommended for stainless steel (use the nickel or ceramic anti-seize tape)
- Contains copper powder, so acids can react with it
- Adds about 0.46mm to the diameter of the threaded portion when applied as directed, so check tolerance
- Use 12mm tape for components up to 38mm diameter and 19mm tape above 38mm, overlap the tape 50% on each wrap
