OMG U-Flow Seals are mechanical compression seals used on all Hercules Retrofit Roof Drains in 80 mm, 100 mm, 125 mm and 150 mm sizes.
U-Flow Screwdrivers are used to install U-Flow Seals. The long 317.5 mm shaft ensures ease of reach when tightening the U-Flow Seal connection screws, and all U-Flow screwdrivers come with a loss prevention bar.
Features & Benefits
- U-Flow Seals exceed the ANSI/SPRI RD1 standard for back flow prevention.
OlyFlow RetroDrains are designed to replace existing drains in re-roofing applications. U-Flow seals help to provide a watertight connection to the existing drain leader.
