Graphite Cup leathers are sealing components commonly used in certain types of valves and pumps to create a tight seal between moving parts, such as a piston or plunger, and the surrounding casing or cylinder. They’re shaped like a cup, with a tapered or rounded bottom and a flared or lip-like opening. They’re usually installed in a recess or housing and pressed against the surface to create a seal. Cup leathers are known for their durability, resilience, temperature resistance, and flexibility, enabling them to effectively prevent leakage and maintain a secure seal even under varying pressures.
