Made of 6061 billet anodized aluminum
This adapter will allow you to use our lights if your drain plug is plastic or metal (see pics) and not 1/2" pipe thread. You will only need this adapter if you have a plastic or metal drain and the threads are 1-1/8"inch across. This adapter has a female 1/2" NPT to allow use of our lights with no modification to your drain IF you have a plastic or metal drain plug! You DO NOT need this adapter if you have a regular 1/2" NPT (pipe thread). It works like your existing plastic or metal drain, allowing you to drain the boat/bilge without removing the light. This adapter most COMMONLY is used on the stainless type two stage drain plugs that have a flat piece that you use your fingers to install. See photos.
