This 3/4 inch drain features an O-ring which, together with the tapered pipe thread, forms a completely leak-free seal between the plug and the flange. The T-handle garboard drain assembly is designed specifically for competition ski boats with their unique hull and interior configurations. The flange is threaded from the backside so the plug can fit inside the boat. The T-handle is long and easily accessible to avoid fumbling through dirty bilge water. It also incorporates a hex for wrench operation. Brass flange, red bronze plug; bulk packaged in 50 per box.
