Description
Prevost Male Coupler - High Flow Profile
Prevost ERC 07 Male Couplers combine the 7.4 mm / nominal 3/8" High Flow quick-connect profile with male NPT connections for compressed-air piping, manifolds, hose assemblies, and pneumatic equipment.
Each model uses the same ERC 07 High Flow coupling interface and is designed for compatible ERP 07 High Flow plugs. Choose between 1/4", 3/8", and 1/2" male NPT connections according to the female-threaded connection on the installation.

Choose the Correct Male Connection
1/4" MNPT
ERC 071251 pairs the High Flow coupling profile with a 1/4" male NPT connection.
3/8" MNPT
ERC 071252 provides the same High Flow interface with a 3/8" male NPT connection.
1/2" MNPT
ERC 071253 combines the ERC 07 profile with a larger 1/2" male NPT connection.
High Flow Profile vs. Male NPT Size
The quick-connect profile and threaded connection serve separate functions.
- The ERC 07 High Flow profile determines plug compatibility.
- The MNPT size determines the female-threaded component into which the coupler installs.
- All variants use the same High Flow quick-connect interface.
- A 1/2" MNPT coupler does not use a different plug profile than a 1/4" MNPT coupler.
ERC 07 / ERP 07 Compatibility
- Coupler family: ERC 07
- Compatible plug family: ERP 07
- Profile: 7.4 mm / nominal 3/8" High Flow
- Confirm the mating plug profile independently from its thread or hose connection.
- Do not force plugs from incompatible profiles into the coupler.
Common Applications
Air Distribution
- Compressed-air piping
- Air manifolds
- Machine drops
- Workstation connections
- Shop air systems
Pneumatic Equipment
- Air tools
- Hose assemblies
- Production equipment
- Service equipment
- Maintenance systems
How to Select the Correct Coupler
- Step 1: Confirm that the mating plug uses the ERP 07 High Flow profile.
- Step 2: Determine the female NPT connection size on the equipment or piping.
- Step 3: Select the corresponding 1/4", 3/8", or 1/2" MNPT coupler.
- Step 4: Verify system airflow, pressure, and service requirements.

Installation & Safety Guidance
- Depressurize the air system before installing or removing the coupler.
- Confirm the required male NPT connection size.
- Apply a suitable thread sealant according to the installation requirements.
- Do not overtighten the coupler into the mating component.
- Confirm the mating plug uses the compatible ERP 07 High Flow profile.
- Inspect the connection periodically for leakage, wear, or damage.
- Replace damaged components before returning the system to service.
Frequently Asked Questions
Which High Flow profile do these use?
All variants use the ERC 07 7.4 mm / nominal 3/8" High Flow profile.
Which plugs are compatible?
Compatible ERP 07 High Flow plugs.
What male thread sizes are offered?
1/4", 3/8", and 1/2" male NPT.
Does changing the MNPT size change plug compatibility?
No. All three variants retain the same ERC 07 quick-connect profile.
What is the difference between the three SKUs?
The primary difference is the male NPT connection size.
Are these PrevoS1 safety couplers?
No. ERC 07 is the regular High Flow quick-coupler family.
