Description
Prevost Industrial Profile Female NPT Plug - ISO 6150 B
Prevost IRP Industrial Profile Female NPT Plugs provide the mating plug connection for compatible Prevost ISI compressed-air couplers using the Industrial / ISO 6150 B profile. This listing combines the IRP 06, IRP 08, and IRP 11 plug families with multiple female NPT thread sizes so the plug profile and threaded equipment connection can be selected independently.
Prevost manufactures its plugs from nitrided steel for resistance to scratching, corrosion, and repeated connection cycles. Precise standardized dimensions help create a dependable interface with compatible prevoS1 couplers, supporting a secure seal and reducing leakage at one of the most common connection points in a compressed-air system.

Understanding Plug Profile vs. Female Thread Size
The Industrial plug profile and female NPT thread size describe two different parts of the plug and should not be treated as the same measurement.
The IRP profile determines which compressed-air coupler the plug will connect to. The female NPT size determines how the plug attaches to the pneumatic tool, hose fitting, machine, manifold, or other threaded equipment.
- IRP 06: 1/4" Industrial profile
- IRP 08: 3/8" Industrial profile
- IRP 11: 1/2" Industrial profile
- Female NPT size is independent of the plug profile.
- Always verify both dimensions before ordering.

Why Plug Quality Matters
Accurate Profile Dimensions
A properly manufactured plug must conform closely to the dimensions and tolerances required by its connection profile. Correct geometry helps the plug seat properly inside the coupling and maintain a dependable connection.
Reliable Sealing
The plug works together with the coupling seal to create the compressed-air connection. Properly matched Prevost plugs and couplers help reduce leakage at this frequently used connection point.
Durable Construction
Prevost plugs use nitrided steel construction for resistance to scratches and corrosion, helping the connection surface withstand repeated use in professional pneumatic systems.
Industrial / ISO 6150 B Compatibility
These plugs use the Industrial / ISO 6150 B connection profile and should be matched to a coupler from the corresponding Industrial family.
- IRP 06 plugs pair with ISI 06 couplers.
- IRP 08 plugs pair with ISI 08 couplers.
- IRP 11 plugs pair with ISI 11-compatible Industrial couplers.
- Female NPT thread size does not determine coupler compatibility.
- Do not assume plugs from different profile families will interchange simply because the threaded connection sizes are the same.
Female NPT Connection Options
1/4" Female NPT
Available with IRP 06 and IRP 08 Industrial plug profiles for pneumatic equipment using a 1/4" male NPT connection.
3/8" Female NPT
Available with IRP 06, IRP 08, and IRP 11 profile families, providing a broad range of Industrial coupling options for equipment with a 3/8" male NPT connection.
1/2" & 3/4" Female NPT
1/2" female NPT is available with IRP 08 and IRP 11. The IRP 11 family also includes a 3/4" female NPT option for larger threaded connections.

Installation & Safety Guidance
- Depressurize pneumatic equipment before installing or replacing compressed-air fittings.
- Confirm both the Industrial plug profile and female NPT thread size before installation.
- Use appropriate thread-sealing practices for the mating NPT connection.
- Do not force a plug into a coupler with a different connection profile.
- Inspect plugs periodically for excessive wear, corrosion, deformation, or damaged sealing surfaces.
- Replace damaged or excessively worn plugs to maintain dependable coupling performance.
- Do not exceed the pressure, temperature, or service ratings of the coupler, hose, fitting, tool, or other connected equipment.
- Compressed-air systems should be installed and serviced by qualified personnel.

Frequently Asked Questions
Are these couplers or plugs?
These are Prevost IRP plugs, also identified as ISO B adaptors. They are the male plug profile that inserts into a compatible ISI Industrial coupler.
What connection profile do these plugs use?
These plugs use the Industrial / ISO 6150 B profile.
What is the difference between the IRP profile size and female NPT size?
The IRP profile determines which quick coupler accepts the plug. The female NPT size determines which male-threaded pneumatic component the plug attaches to. These are independent specifications.
Which plug fits an ISI 06 coupler?
Use an IRP 06 Industrial plug with an ISI 06 Industrial coupler. This listing includes IRP 06 plugs with 1/4" and 3/8" female NPT connections.
Which plug fits an ISI 08 coupler?
Use an IRP 08 Industrial plug with an ISI 08 Industrial coupler. This listing includes 1/4", 3/8", and 1/2" female NPT options for the IRP 08 family.
Which plug fits the 1/2" Industrial coupling family?
The IRP 11 plug family is used with the corresponding 1/2" Industrial coupling family. This listing includes IRP 11 plugs with 3/8", 1/2", and 3/4" female NPT connections.
What are Prevost plugs made from?
Prevost specifies nitrided steel construction for its plugs, providing resistance to scratching and corrosion.
Why are plug dimensions important?
A plug must conform closely to the required connection-profile dimensions and tolerances so it seats correctly inside the coupler and interfaces properly with the coupling seal.
Does female NPT thread size determine coupler compatibility?
No. Coupler compatibility is determined by the IRP Industrial plug profile. The female NPT dimension only determines the threaded equipment connection.
Can these plugs be used on pneumatic tools?
Yes, when the tool or accessory has a compatible male NPT connection and the compressed-air coupler uses the corresponding Industrial profile.
Why use matching Prevost plugs with Prevost couplers?
Prevost designs its plugs to standardized dimensions and tolerances so they properly interface with the coupling and seal, helping provide a reliable compressed-air connection.
