This adapter is designed to reduce the size of your bilge pump outlet from 1 inch to 3/4 inch. It allows you to adapt your bilge pump to smaller hoses or specific systems, which can be beneficial in applications where space is limited, or a precise water flow is required. The reducer is particularly useful in marine environments, such as on boats, and for water management systems like powered sluice boxes. For optimal durability and a secure connection, it is recommended to print this reducer in PETG and attach it with a suitable waterproof adhesive such as E6000, Shoegoo or silicone. This ensures reliable operation in demanding wet environments.
