The new 35mm drainage bung is made from Nylon 6 which is durable and has a strong U.V. resistance. The plug has good sealing qualities and a high quality Nitrile O’ring and is resistant to today’s fuels and oils. The drainage hole is 35mm and the cut out size for the base is 40mm. The 4 hole layout in the base matches several existing versions currently on the market, including Quintrex, Stacer and Savage. They are available in Black and White to suit all boat colour combinations.
