Automotive Profile vs. Male NPT Size
The 1/2" Automotive profile and the Male NPT connection size describe two different sides of the Prevost PrevoS1 Stainless Steel Male Safety Coupler.
- The 1/2" Automotive profile determines which quick-connect plug fits the coupler.
- The Male NPT size determines which female-threaded component the coupler installs into.
- USI 111252 uses 3/8" Male NPT.
- USI 111253 uses 1/2" Male NPT.
- USI 111254 uses 3/4" Male NPT.
- All three models retain the same 1/2" Automotive quick-connect profile.
Compatible Prevost Plug Family
| Coupler Family | Automotive Profile | Compatible Plug Family | ID Passage |
|---|---|---|---|
| USI 11 Stainless Steel Male Safety Coupler | 1/2" | URP 11 | 1/2" |
The Prevost PrevoS1 Stainless Steel Male Safety Coupler - 1/2" Automotive Profile should be paired with a compatible URP 11 1/2" Automotive Profile plug.
The threaded connection size on the plug does not have to match the threaded connection size on the coupler. Quick-connect compatibility is determined by the Automotive profile.
