Prevost Prolac Hose Stem Coupler Industrial Interchange

High-Safety Connection for Direct Hose Integration

The Prevost Prolac Hose Stem Coupler is a safety-venting pneumatic socket designed for direct insertion into flexible air hoses. By integrating a serrated hose barb (stem) directly into the coupling body, this fitting eliminates the need for extra threaded adapters, reducing weight and potential leak points.

As part of the professional Prolac range, this coupler features a specialized safety mechanism that prevents “hose whip” by venting downstream air pressure before the tool is released, ensuring a safe and efficient work environment.

Key Features

• Anti-Hose Whip Safety System: The Prolac mechanism utilizes a two-stage disconnection process. It safely vents the air pressure from the tool side before releasing the plug, protecting the operator and surrounding equipment from sudden, violent hose movements.
• Integrated Serrated Hose Barb: The hose stem is machined with sharp, deep serrations to provide maximum “bite” into the inner lining of the hose. When secured with a proper clamp, it creates a permanent, high-integrity bond that will not pull out under pressure.
• One-Push Connection Technology: Engineered for speed and ease of use, this coupler allows for a simple one-handed connection. There is no need to pull back a sleeve—simply push the plug into the socket to engage the air supply.
• High-Impact Composite Housing: The body is constructed from technical polymers that are resistant to abrasion, crushing, and shop chemicals. The composite material also protects delicate surfaces (like car paint or finished wood) from scratches if the coupler accidentally bumps the workpiece.
• Universal Interchange Compatibility: Available in various profiles (including Industrial, Automotive, and ARO) to match your existing shop setup, ensuring a seamless transition to a safety-compliant system.

Technical Specifications

Common Applications

• Custom Hose Assemblies: Creating high-safety lead hoses or extension lines for impact wrenches, grinders, and sanders.
• Mobile Air Service: Ideal for service trucks and mobile mechanics who require rugged, lightweight, and safe hose connections.
• Manufacturing Plants: Providing safe air connections on assembly lines where workers frequently change pneumatic tools throughout the shift.
• Construction Sites: Securing air lines for framing nailers and pneumatic drills in rugged, outdoor environments.

Installation Tip

For the most secure connection, always use a high-quality ear clamp or worm-gear clamp over the hose at the barb location. Ensure the hose is pushed completely over the serrated stem so that the end of the hose sits flush against the coupling shoulder before tightening the clamp.
