About This Product

Advanced Drainage Systems, Inc. (ADS) 12 in. Singlewall Split Coupler is designed to join two 12 in. corrugated singlewall pipe sections together. The split coupler is ideal in applications where lightweight and easy-to-install couplers are needed. Additionally, the split coupler can be used to repair an existing pipe that has been cut. Made of high density polyethylene (HDPE), the split coupler is designed to last the life of the drainage system. ADS singlewall fittings are the right choice for your residential and commercial drainage projects.

Answer This Question

Is this coupler easy to remove and reattach, leaving the split at the top of the joined 5" flex pipes? We have one 10' flex pipe ending under deck and need to temporarily attach another 10' pipe just during rain. Twisting on/off too difficult

            Answer This Question

            Pipe has a 4.6" OD and the split coupler is larger. Suggest at least a 6" clamp to go around the coupler.

              I use to patch a hole on top of drain pipe. I wouldn't recommend if the hole is too close to the bottom. There isn't a sealer that can be used with it except for there NDS tape, which works well also. You can also cut in half lengthwise for small hole.

              Item was well made but was too small for culvert pipe that I already had in the ground . Not a universal fit . It was for a 12” pipe but would not fit my application .

              Easy installation and met my expectations. I had to install 2 couplings on each side of my driveway to extend the 12 plastic pipe that I sleeved through the existing concrete culvert pipe under my driveway.
