Parker Series 7084 Twinhammer Hose is the first factory-assembled dual hose system that delivers both air and w ater in a single, unitized configuration for dust suppression in jackhammer/breaker tool applications, as required by new OSHA Respirable Crystalline Silica (RCS) requirements.

The new tw in line hose system concurrently:

  • transfers air to pow er heavy duty pneumatic tools
  • transfers water to suppress silica dust produced by tool operation
  • helps create a safer and more efficient work environment

Twinhammer hose assemblies feature durable, abrasion resistant and chemically bonded lines that provide easy handling while eliminating intrusive clamps, straps, tape or zip ties. The assemblies incorporate crimped-on universal end styles for quick connection/disconnection to the air system, and rust resistant crimped-on brass male NPT couplings for easy attachment to the water system.
