Hose Friction Loss Charts
- The key to getting large amounts of water to the fire scene faster is to reduce friction loss. There is no better way to reduce friction loss than to use Snap-tite’s Ponn Conquest. Conquest reduces friction loss by up to 50% as compared to other hose designs to deliver more water at standard operating pressure.
