45mm Coarse Thread Drain Plug and Housing Flat Base
Choose 45mm coarse thread drain plug and housing - flat base to match the drain fitting on your boat. This listing combines the plug and housing, so both mating components can be selected together.
The flat base allows the fitting to be mounted low in the boat. Check the listed hole diameter and the available space around the base; the flat-base profile is an important distinction from a round housing.
Inspect the existing housing and sealing surfaces when replacing a drain plug. Confirm the correct fit before use rather than assuming that every marine bung shares the same dimensions.
Choosing and using this product
Keep service points accessible and follow the relevant system instructions for fastening, sealing and hose support. Avoid forcing a hose or thread to compensate for an unsuitable fitting. Confirm the finished connection and normal system operation before putting the installation back into use.
For a replacement, inspect the existing fitting and adjoining hose before ordering. Consider the direction of the connection as well as its size. An elbow, straight fitting or barbed tail changes the route and clearance needed even when the nominal connection size is similar.
Check the stated contents when putting together the plumbing run. A fitting-only listing does not necessarily include hose, clamps, seals or a mounting assembly. Lay out the required connections before installation so the finished arrangement can be checked as a whole.
When comparing alternatives, use the specified material and intended application rather than assuming every marine fitting is suitable for every liquid. Keep the part reference with the plumbing records so future spares can be matched to the connection actually installed.
Plan the connection from the system outward: identify the fluid application, mating thread or hose size, and the space available for the fitting. A nominal pipe-thread size is a separate measurement from a hose diameter, so compare the correct dimension at each connection.
