Yale Y2000 Clamp Closure

Our Yale Y-2000 is designed for line applications for which a simple clamp operation offers an alternative to traditional threaded closures.


Our Yale™ Y-2000 is a clamp-style closure designed specifically for 8- through 12-in. pipeline applications. The operation is simple, safe, does not require special tools, and does not place the operator in harm's way during any step of the opening process. Our standard design codes are ASME B31.4 and B31.8.
