LEH has set its sights on being the premier couplings provider for North America and beyond.  No matter what the application is hydraulic, pneumatic, or plug-in technology.  LEH has you covered!



LEH Hydraulic couplings are suitable for applications with operating pressures up to 4640 PSI (320 bar) for both industrial and mobile hydraulics. By using LEH Hydraulic couplings, pollution through hydraulic fluid leakage is reduced and helps to protect the environment from harm. Presented here are couplings, nipples, and pressure testing systems for hydraulic applications.  Complete X-Series Flat Face Coupling Line.   



LEH pneumatic product line includes the world’s best-performing quick connect couplings, blowguns, polyurethane hoses, lightweight and heavy-duty hoses, cable reels and accessories. Leading Edge offers all the necessary components, from FRL units to compressed air couplings, to ensure reliable compressed air performance worldwide.


As more and more applications industry-wide are being converted from threaded to plug-in connectors, NexConnect Plug-In hose fittings are the connection of choice for critical equipment applications.  NexConnect Plug-In hose fittings simply “plug in” to hydraulic systems. NexConnect fittings are available in sizes 1/4" through 1" with maximum working pressures of up 5075 PSI (350 bar).  More info on the NexConnect Plug-In.


Multi-X is a range of innovative, easy to handle, multi-plates designed to meet and exceed the demands of even the most challenging mobile hydraulic applications.  More info on the Multi-X



X-64 pressure elimantor couplings solve problems with high connection force due to residual pressure on the nipple side.  More info on the X-64.
