Features & Benefits

  • Twin-Kam™ arms feature a unique detent position that helps prevent accidental release. Even with both arms partially opened, the Twin-Kam detents hold the adaptor more firmly in the coupler. All arms are Guaranteed For Life (GFL).

  • Spring-Ring™ design prevents finger rings from getting trapped under the arms, ensuring proper closure.

  • Constructed of 316 Stainless Steel

  • ¾" to 4" sizes


Because of its unique poppet action the OPW Kamvalok® Dry Disconnect virtually eliminates spillage of any residual liquid contained within the line after disconnection. Kamvaloks® are used at transfer points where product loss is unacceptable. Common applications include: paint, lacquers, inks, adhesives, fatty acids, pharmaceuticals, liquid soaps, petroleum products, solvents, ag-chemicals, vegetable oils, detergents, diesel exhaust fluid (DEF) and many acids and caustics.
