Davey 49021SP - 16mm Silicone Carbide Seal

Davey 49021SP - 16mm Silicone Carbide Seal - A seal hard enough to outlast the pump. Most pump seals wear out on their faces. The Davey 16mm silicone-carbide seal is the answer to that — its faces are made from one of the hardest materials going, so it shrugs off the grit and heat that chew through a standard seal. Carrying Davey's part number 49021SP, it's the 16mm shaft seal across Davey's Power Master, Power Chief and Power Ace pump ranges. The Viton elastomer adds chemical resistance on top, so it holds up where softer seals score and start to weep. It costs more than a basic seal because it lasts far longer in the conditions that destroy them — fit it once and forget it. Features Silicon-Carbide Faces: One of the hardest sealing materials available — resists the grit and heat that score softer seals. Power Master, Chief & Ace Fit: The 16mm shaft seal across Davey's Power Master, Power Chief and Power Ace pumps. Viton Elastomer: Adds chemical resistance for a longer life in hot, treated water.
