The ASHLAND WATER GROUP PPL-103 is a cup leather seal designed for use in pitcher pump assemblies. This formed leather cup creates the compression seal that allows a pitcher pump to draw and displace water by maintaining tight contact against the pump cylinder bore. At 3 inches outer diameter and 2 inches inner diameter, it is a direct-fit replacement seal for compatible pitcher pump configurations. Plumbers and pump service technicians install this part as a routine wear component. The leather construction provides natural compliance and self-lubrication against the cylinder wall, which is characteristic of traditional pitcher pump service.
Cup leathers are a standard replacement item in pitcher pump maintenance. Pitcher pumps are commonly found in rural residential water systems, irrigation applications, hand-pump wells, and agricultural settings where a simple, manually operated piston pump draws water from a shallow well or cistern. The PPL-103 is sold in packages of 6 units, making it practical for technicians servicing multiple pumps or stocking a parts inventory for seasonal pump service work.
Designed as an OEM-style replacement cup leather seal for pitcher pump assemblies requiring a 3-inch by 2-inch leather cup seal.
Installation is typically performed by a licensed plumber or experienced pump service technician. Before disassembly, relieve any system pressure and disconnect the pump from the water source. The cylinder bore should be inspected for scoring or wear before installing the new cup leather. Soak the leather cup in light oil or water prior to installation to condition the material and ease seating in the bore.
