A Coupler Revolution! A French-born, Leak-Free Coupler Backed by a 3-Year Warranty!
The polymer cushion ensures that the body will not be scratched, even if it hits equipment, making the handling of air tools even easier. By providing a stable air supply, equipment performance is maximized, and long-term performance maintenance is enabled.
The Leak-Free Coupler
Air leaks occur everywhere, but many of them happen at joints, hose connections, and couplers. There is always a root cause for leakage. Prevost couplers are the highest quality couplers, born from relentlessly pursuing the causes of leaks and continuously applying continuous improvement.
The design allows for easy and safe connection and disconnection via a simple button push.
The body is made of highly durable synthetic resin, which reduces the risk of deformation or damage. These pneumatic components are designed to prevent leaks from the outset.
The Principle of Leak Prevention

Conventional Couplers
Most air leaks occur due to the deterioration of the packing used to create an airtight seal when the adapter is connected. By design, conventional couplers place a significant load on this packing, leading to deterioration over time and creating gaps that allow for leakage.
Prevost Couplers
Prevost couplers feature an internal valve structure with a two-stage sealing mechanism. Additionally, the innovative design minimizes the load placed on the adapter-side seals, resulting in a structure that is highly resistant to deterioration.
