Prevost Male Coupler – Automotive Interchange
Threaded Precision for Secure Pneumatic Connections
The Prevost Male Coupler – Automotive Interchange (Tru-Flate Style) is the ideal safety fitting for applications requiring a direct threaded connection to a hose, manifold, or pipe drop. Featuring a Male NPT thread, this coupler is designed to screw directly into female-threaded fixtures or hose ends, providing a rigid and leak-free interface for your compressed air tools.
Built with Prevost’s industry-leading prevoS1 safety technology, this coupler prevents the dangerous “hose whip” that occurs when disconnecting pressurized tools. With a simple push of the button, the coupler automatically vents downstream pressure before releasing the plug, ensuring maximum safety for mechanics and operators in automotive environments.
Key Features
- Male NPT Connection: Equipped with precision-machined male threads, making it the perfect choice for installing into wall manifolds, distribution blocks, or hoses with female swivel ends.
- Automotive Profile (Tru-Flate): Designed specifically to mate with standard “T-Style” (Tru-Flate) plugs, commonly used in North American tire shops, collision centers, and service garages.
- One-Push Safety: The patented 2-stage mechanism vents air pressure before releasing the tool. This eliminates recoil, reduces noise, and prevents accidental injury.
- Non-Marring Body: The body is constructed from a high-grade, scratch-resistant composite. Unlike metal couplers, it won’t chip paint or dent vehicle bodywork if dragged across a surface.
- Energy Efficient: Engineered with high-quality internal seals to prevent air leaks, helping your air compressor run more efficiently and reducing energy costs over time.

Why Choose a Male Coupler?
While female couplers are standard for pipe ends, Prevost Male Couplers are essential for custom builds. They are frequently used to build custom distribution manifolds or are screwed into the end of a hose that has a reusable female fitting. The composite body is tough enough to withstand being dropped on concrete floors yet light enough to reduce operator fatigue.
Ideal Applications
- Custom Manifolds: Screwing directly into a multi-port distribution block to create a custom “power bar” for air tools.
- Hose Assemblies: attaching to rubber or PVC hoses that feature crimped female ends.
- Automotive Workshops: Upgrading tire changers and impact wrench stations to OSHA-compliant safety standards.
Installation Tip
Since this coupler has Male NPT threads, apply a high-quality thread sealant or PTFE tape to the threads before screwing it into your manifold or hose fitting. Tighten securely to ensure a leak-proof bond with your compressed air piping system.
