Packing wipers are essential components in valve and pump systems, designed to prevent contamination and retain lubrication. Made from resilient materials like PTFE, nylon, or elastomers, these wipers effectively remove debris and excess fluids from sealing surfaces, ensuring smooth operation and extended equipment lifespan. Widely used in hydraulic and pneumatic systems across industries such as aerospace, automotive, and manufacturing, packing wipers contribute to enhanced equipment performance and reliability.
