Overview The Professional Heavy Duty Mortar Couplings Plug with Hose Stem is engineered for pumping mortar, plaster, or screed. This product offers exceptional operational safety and ensures maximum material flow to your machine. Design Features These mortar couplings operate as lever couplings; however, they are not compatible with standard Kamlock couplings. The connection mechanism is straightforward: the female and male parts, constructed from malleable cast iron or steel, are secured via two handles. Notably, Type 25 is designed for single-handed operation.
