Hi! Thank you for asking about the 18" ADS culvert split coupling. This coupling is made of plastic and should, therefore, be used on a plastic culvert pipe. A corrugated pipe can be made of steel or polyethylene (plastic). It is best if you confirm what type of corrugated pipe you have, the one that you want to connect to your steel pipe, and what the dimensions of it are. After we have determined such information, only then can we recommend the right coupling you should use to connect both of your pipes. We are looking forward to hearing from you soon. We do hope we could assist you further on this matter. Should you have further questions, please ask away! Thank you for visiting Have a great day!
