PTFE PTFE Thread Seal Tape are supplied to our own published dimensions — this is a trade-series article rather than one covered by a dimensional standard, so confirm the figures against the part you are replacing. The grade provides near-universal chemical resistance; no elastic recovery, so it is used as a back-up or energised seal and is non-magnetic; the practical service range is approx. -200 °C to +260 °C.
Why Choose PTFE for PTFE Thread Seal Tape
Chosen for chemical service and low friction rather than for elastic sealing. For ptfe thread seal tape, this matters when near-universal chemical resistance; no elastic recovery, so it is used as a back-up or energised seal is the primary requirement.
Mechanical & Physical Properties
| Grade designation | polytetrafluoroethylene (thermoplastic, not an elastomer) |
|---|---|
| Magnetic response | Non-magnetic |
| Service temperature | approx. -200 °C to +260 °C |
| Corrosion characteristic | Near-universal chemical resistance; no elastic recovery, so it is used as a back-up or energised seal |
Galvanic & Galling Considerations
Galvanic and galling behavior do not apply to ptfe thread seal tape in PTFE — the relevant compatibility questions are chemical: confirm the elastomer against the fluid, the temperature and any cleaning agents in service, and check the gland or groove dimensions give the intended compression on the section.
Comparable Grades
For ptfe thread seal tape, consider an energised or spring-loaded PTFE seal where recovery is required, or FKM where the chemistry allows an elastomer. Elastomer selection is decided by the medium, the temperature range and whether the seal is static or dynamic — not by strength.
Sizes of PTFE Thread Seal Tape Available in PTFE
| Colour | Density | Intended service | Notes |
|---|---|---|---|
| white | standard density | water and general plumbing | general purpose |
| pink | high density | water, larger threads | thicker, fewer wraps needed |
| yellow | high density | gas lines | gas-rated tape |
| green | oil-free, degreased | oxygen service | must be oxygen-clean |
| grey | with filler | stainless steel threads | reduces galling on stainless |
Dimensions are independent of the material: every size above is available in PTFE.

Need this seal in a grade that is not listed?
Ptfe is one of the grades the catalog describes. Inside diameter, cross-section and compound are the three that matter, and the compound is chosen against the fluid and the temperature rather than the dimensions.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
