- May be used as part of an OSHA-compliant silica dust suppression system

The Parker jackhammer retrofit kit can be used as part of an OSHA-compliant wet method hose system for silica dust suppression.

The mandated compliance date of the new silica rule for the construction industry is September 23, 2017.

The kit includes the hardware and attachment components to install/retrofit Parker Twinhammer hose onto many models and generations of traditional jackhammers:

• Jumper hose
• Thread tape
• Hose couplings/connectors
• Straps
• Pressure regulator
• Storage bag
• Water valve
