100 vs 125 vs 200 pipe threader classes
Compare ratchet pipe-threader max-die ceilings against PipeNPT estimates, with verified VEVOR US product examples and an honest NO_MATCH path.
| Class | Clears when | Typical fit | Trade-off |
|---|---|---|---|
| 100 · 3-die · max 1 in NPT | pipe_npt ≤ 1.0 in | Common 1/2–1 in NPT jobs | Too small once size clears 1 in |
| 125 · 4-die · max 1-1/4 in NPT | pipe_npt ≤ 1.25 in | Jobs that clear 1 in but stay within 1-1/4 | Still short beyond 1-1/4 in |
| 200 · 6-die · max 2 in NPT | pipe_npt ≤ 2.0 in | Heavier jobs through 1-1/2 and 2 in | Largest class on this ladder |
| NO_MATCH (above ladder) | pipe_npt > 2.0 in | Size beyond this site’s published ceiling | Do not force the 200 class — size up outside this screen |
