Deluxe Coarse-Thread Drain Plug and Washer Each for Boat Plumbing - RWB1947

Deluxe Coarse-Thread Drain Plug and Washer Each. This replacement plug-and-washer option belongs to the deluxe plastic drain range. The range is Australian made and uses a coloured plastic washer and retainer-lug arrangement. Coarse-thread and fine-thread replacement versions are different products, so the exact thread type is central to choosing the correct spare. This listing supplies replacement plug and washer components rather than a complete drain body. The associated drain's 17mm flow opening and 25mm cut-out are reference dimensions for the complete installation, not a substitute for checking the plug thread.

Choosing and using this product

Identify the existing drain and examine its thread before ordering. A fine-thread plug should not be forced into a coarse-thread body, or vice versa. Compare the old plug with the selected replacement and confirm the intended range if the existing fitting is unmarked. Inspect the body threads and sealing face while the old plug is removed. Renewing the plug and washer will not correct damage elsewhere in the drain. Clean the mating surfaces, fit the replacement squarely and check that the washer seats properly. Test the closed drain for leakage before returning the boat to use, following the normal pre-launch procedure. If the plug does not engage smoothly, stop and check compatibility rather than tightening it further. Check the pack quantity carefully: individual and pair options are separate listings. Store spare components clean and together so that the matching washer is available when needed. Inspect the fitted washer during routine maintenance and recheck the drain whenever it has been opened for cleaning or draining. Keep the thread type identifiable with the boat's spare parts.
