Sleeve Bolts have changed color from Black to a Gray to ensure proper installation.

VIQUA Sleeve Bolt (602665)



New sleeve bolt from VIQUA designed to reduce the risk of misaligning the quartz sleeve when placing into the UV chamber.

  • This new bolt is grey, rather than black, to better distinguish between the existing sleeve bolt and lamp bolt.
  • Only requires one o-ring so less likely to pop out when operator forgets to depressurize UV system before putting in lamp. 
  • This sleeve bolt (602665) is utilized in VIQUA D4, E4 and F4 series systems. 
  • Be sure to wear gloves when you change the UV lamp, and always use genuine VIQUA lamps to ensure optimal performance and keep the integrity of the system.
