Ashland Water Group PPL-503 Flat Leather Pump Cup 3.5 in

Product Description

The ASHLAND WATER GROUP PPL-503 is a flat leather pump cup designed as a replacement sealing component for pitcher pump assemblies. Measuring 3.5 inches in diameter and 1.875 inches in height, this leather cup provides the flexible, compressible seal required for the piston stroke in hand-operated pitcher pumps. Leather cup seals are a traditional and reliable choice for low-volume water transfer applications. Plumbers and pump service technicians install these during routine pump rebuilds or when an existing cup has dried out, cracked, or lost its ability to hold prime.

This flat leather cup is suited for use in residential and light-duty agricultural pitcher pump installations where a standard piston-style hand pump is used to draw water from a shallow well, cistern, or holding tank. It is a direct replacement style component for pitcher pump maintenance and repair. Each unit is sold individually, though the package quantity from the supplier is 6 units per pack, making it practical for stocking multiple rebuilds at once.

Key Features

• Flat leather construction provides a flexible, self-conditioning seal during pump operation
• 3.5-inch diameter fits standard pitcher pump cylinder bores
• 1.875-inch height provides adequate piston cup depth for consistent sealing stroke
• Leather material naturally swells when wet, improving suction and seal integrity
• Lightweight at 1.25 pounds per unit, easy to carry and stock on service vehicles

Compatibility

Designed as an OEM-style replacement leather cup for standard piston-style pitcher pump assemblies requiring a 3.5-inch flat leather seal.

Installation Notes

Installation is typically performed by a plumber or pump service technician. Before replacing the pump cup, relieve any water pressure in the system and disconnect the pump from its water source. Soaking the leather cup in water or light oil before installation helps condition the material and improves initial sealing performance. Follow all applicable local plumbing codes when servicing well or cistern pump equipment.
