Yale® Hammer Unions

R&M Energy Systems supplies a wide assortment of Yale® Hammer Unions for various services such as tank battery applications, production hook-ups and stand-by manifolds. The Yale line of hammer unions is engineered for maximum versatility:

• Seven figure models
• Sizes from ¼" through 8"
• Over 30 available models feature pressures range from 500 PSI to 12,500 PSI
• Threaded and butt weld configurations

The sealing action of Yale Hammer Unions is not dependent upon metal-to-metal contact. An elastomeric O-ring fits in a precision-machined groove between the metal mating parts. Forced into sealing position at very low initial pressure, the O-ring ensures the utmost safety dependability and economy despite severity of service conditions.
