MIP vs NPT Fitting
Here is a brief comparison table between NPT vs MIP fitting that used in piping systems.
MIP vs NPT Fitting
| NPT | MIP | |
|---|---|---|
| Stand for | National Pipe Tapered threads | National Pipe Tapered threads |
| Known as | ANSI/ASME B1.20.1 pipe threads | Copper or steel fittings |
| Material | PVC, Plastic | Iron, copper, stell, pvc, plastic |
| Application | Residential water & hydraulic systems | Residential, commercial and industrial piping systems |
| NPT Fitting | MIP Fitting | |
| Shape | Angle between taper and center axis | Straight |
| Pitch measuring | Threads per inche (TPI) | Threads per inche (TPI) |
| Truncation of roots and crests | Flat | Flat or not |
| High-pressure applications | Not recommended | Recommended |
| Tightening | General tightening standard is recommneded | N/A |
| Compatible | FNPT fittings | FIP fittings |
| Sealant | Sealant compound or PTFE (Polytetrafluoroethylene) tape | Pipe dope or Teflon tape |
NPT and NPT fitting
NPT stands for National Pipe Taper that refers to residential-grade pipe systems. An NPT fitting is a National Pipe Tapered threads fitting that can be used with FNPT (female NPT) fitting in residential water and hydraulic systems.
MIP and MIP Fitting
MIP stands for Male Iron Pipe that refers to heavy-duty-grade metal pipe systems. A MIP fitting is a metal threaded-piping fitting that can be used with a FIP (female iron pipe) fitting in heavy-duty piping systems for both residential and industrial uses.
