W Cooper Lock Ring [T Series Trap] (6576) is a W. Cooper Industries lock ring for compatible T Series trap assemblies. The lock ring helps secure the trap lid or related trap body components, making it important for maintaining a tight, serviceable connection. It is a practical replacement when the original ring is cracked, worn, stripped, or difficult to tighten evenly. Trap components are frequently opened for basket cleaning and pump maintenance, so the lock ring must remain in good condition to support reliable operation. Before installation, compare the part number and trap series with the existing assembly. It is also smart to inspect the lid, trap body, and O-ring at the same time, since worn sealing surfaces can contribute to leaks or air intrusion even after the lock ring is replaced.
