Prevost Male Coupler: High Flow Profile (ESI Series)

Description

Prevost Male Coupler: High Flow Profile (ESI Series)

The Prevost ESI Series Male-Threaded Coupler is a heavy-duty, one-stage safety coupling engineered for the European High Flow (7.2 – 7.4mm) profile. Featuring the industry-leading Prevo S1 safety technology, this coupler allows you to upgrade your pneumatic system to a safer, high-capacity platform that delivers maximum power to your tools.

Designed with a male-threaded inlet, this specific model is perfect for attaching directly to air manifolds, portable compressors, or the end of leader hoses where a secure, fixed connection is required.

Key Performance Features

• Prevo S1 Safety System: Protect your workspace and staff with a controlled “venting” disconnection. With one push of the button, the coupler exhausts downstream air pressure before releasing the plug, completely eliminating the risk of dangerous hose whip.
• Unrestricted High Flow: The ESI profile is designed to provide massive air volume (up to 1,820 L/min). It is specifically built to prevent the pressure drops that cause impact wrenches to lose torque and grinders to bog down.
• Impact-Resistant Composite Body: The high-tech “non-marring” composite housing is designed for longevity. It is crush-resistant and won’t scratch car paint or polished surfaces if it accidentally bumps into a workpiece.
• Leak-Free One-Handed Operation: The ergonomic green button makes tool changes fast and effortless. Simply push once for a secure, airtight lock that saves energy and reduces compressor cycling.
• Weather & Chemical Resistant: The composite material is naturally resistant to corrosion and harsh shop chemicals, ensuring the internal mechanisms remain smooth and responsive over years of service.

Technical Specifications

Common Use Cases

• Compressor Outlets: Screw directly into your portable compressor’s tank outlet to ensure your high-flow hoses get the maximum CFM from the start.
• Manifold Systems: Ideal for rigid pipe systems where tools are frequently swapped.
• Leader Hoses: Perfect for attaching to the end of a whip hose to provide a safe, high-flow junction point.

The “Green Button” Identification

In the Prevost ecosystem, the Green Button signifies the ESI (Euro High Flow) profile.⁹ To ensure a perfect, leak-free seal and maximum airflow, always pair this coupler with Prevost ERP Series male plugs.
