OPW Engineered Systems has long been recognized as the company that sets the standard when it comes to API Bottom-Loading Couplers. Our API couplers have been used in many industries. The 1004D3 and Lynx has been designed to be the safest, cleanest and fastest way to load transports.

OPW now looks to raise the bar with the introduction of the Lynx Coupler – the next generation in API Bottom-Loading Couplers from OPW. By combining ease of maintenance with a unique U-pin design, loading-arm operators can perform coupler maintenance without special tools and do it quickly.
