Prevost Female Coupler – Automotive Interchange (Tru-Flate)
The Ultimate Safety Upgrade for Automotive Workshops
The Prevost Automotive Interchange Coupler (Tru-Flate Style) is designed to bring premium industrial safety and performance to the standard automotive environment. Built to compatible with the “T-Style” or Tru-Flate plugs commonly found in garages and tire shops across North America, this coupler eliminates the dangerous “hose whip” associated with traditional fittings.
Featuring Prevost’s patented prevoS1 one-touch safety technology, this coupler allows you to disconnect tools with a single button press. The mechanism automatically vents the downstream pressure before releasing the plug, ensuring your technicians stay safe and your equipment remains undamaged.
Key Features
- Zero-Pressure Disconnect: The 2-stage safety mechanism vents compressed air before releasing the plug. This prevents the hose from whipping back and injuring the operator or damaging vehicle finishes.
- Universal Automotive Fit: Designed specifically to mate with standard Tru-Flate (T-Style) plugs, allowing you to upgrade your wall drops and hose reels without replacing every tool plug in the shop.
- Non-Marring Composite Body: Unlike heavy brass or steel couplers that can scratch paint or dent fenders, the high-impact composite body is lightweight and tough, making it ideal for working around vehicles.
- Leak-Free Efficiency: Precision-molded seals prevent the costly air leaks common in cheap hardware store couplers, ensuring your air compressor runs less often and saves energy.
- Ergonomic Design: The button is easy to operate even when wearing greasy gloves, and the push-to-connect feature makes swapping impact wrenches and tire inflators instant and effortless.

Why Upgrade Your Shop?
In a busy automotive environment, air leaks are money wasted. Standard brass couplers wear out quickly, leaking air and forcing your compressor to cycle continuously. Swapping to Prevost Safety Couplers not only secures your air system against leaks but also modernizes your workflow with rapid, safe tool changes that reduce operator fatigue.
Ideal Applications
- Tire Shops: Rapidly changing between impact guns and tire inflators without fighting line pressure.
- Auto Body Repair: Using lightweight, scratch-resistant couplers that won’t damage fresh paint.
- General Mechanics: upgrading standard “shop air” lines to a safer, OSHA-compliant standard.
Installation Tip
This is a Female NPT coupler, meaning it threads onto a male pipe nipple or a hose with a male end.9 When installing on your compressed air piping drops or hose reels, use a high-quality thread sealant to ensure a permanent, airtight seal at the thread connection.
