PRODUCT IMPROVEMENT –
New TOUGH GUN TT3 Reamer Check Valve

April 15, 2017

The check valve on the TOUGH GUN® TT3 and TT3E reamer robotic nozzle cleaning stations have been upgraded to a more robust and durable design. The new check valve is now common between both the analog and the Ethernet model.

Important Notes:

  • The new check valve will keep the same part number as the check valve previously used on the TOUGH GUN TT3E reamer Ethernet model: TT3E-500-20.
  • Check valve part # SR-500-20 previously used on the TOUGH GUN TT3 reamer analog model will be replaced with the new check valve (part # TT3E-500-20).
