Coarse Thread Drain Plug
Choose coarse thread drain plug - bulk to match the drain fitting on your boat. This plug-only option lets you replace the removable component when the matching housing remains suitable.
Check the coarse-thread specification against the existing fitting before ordering. Matching the thread and any stated housing reference is more reliable than choosing by appearance alone.
This is the bulk format, supplied in packs of 10. The separately coded prepacked option has a different pack quantity, so compare the full product code when ordering.
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
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.
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.
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.
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.
