HydroFlame™ Pro Water Module

The HydroFlame Pro Water Module provides additional water protection for HoldRite HydroFlame Pro Series sleeves and prevents debris from falling into annular space around piping. Use of a water module is fully optional and is not required to obtain a W rating. The mid-body seal in standard HydroFlame Pro Series sleeves already provides a UL W rating (refer to UL System data for specific sizing requirements). 

Key features: 

  • Pre-installed prior to concrete pour 
  • Available for all HoldRite HydroFlame Pro Series Sleeve sizes 
  • Adds ½ inch to the overall height of HydroFlame Pro Series sleeves 
  • Secures to safety cap and other HydroFlame Pro Series accessories 
  • UL W-rated seal, watertight for most penetrants. Refer to UL System data for specific size requirements
