OSHA Jackhammer Construction Silica Standard

New Wet Spray
Hose System for Silica
Dust Suppression

Parker’s new Twinhammer Hose is the first factory-assembled dual hose system that delivers both air and water in a single, unitized configuration for dust suppression in heavy duty pneumatic jackhammer applications.

Chemically bonded lines –
easy handling and installation
  • Permanently and continuously joined. No improvised field attachment or maintenance of intrusive clamps, straps or zip ties that loosen, get snagged, impede efficiency and become potential safety hazards.
  • Factory split-back at each end, allowing easy attachment to air compressors, water supply and jackhammers
Color coding – quick identification
  • Red 3/4” abrasion-resistant 300 psi hose for air service
  • Blue 3/8” abrasion-resistant 300 psi hose for water spray/dust suppression service
Permanent crimp couplings – secure,
maintenance-free connections
  • Carbon steel universal air hose couplings to quickly connect/disconnect the tool and air supply
  • Rust-resistant brass male NPT water hose couplings to easily attach the water supply and spray nozzle


Note: The Twinhammer air hose is rated to 300 psi maximum
working pressure. Finished hose assembly is rated to 150 psi due to limitation of the industry preferred fitting end
style/connection.
