4 Inch ABS Cleanout Adapter, ABS Construction. This particular fitting is a Cleanout Adapter for ABS Pipe applications and has a solid ABS (Acrylonitrile Butadiene Styrene) construction. It has a 4 inch nominal size and is for use with 4 inch fittings and pipe. This cleanout adapter has two pieces; an adapter and a threaded plug. The adapter fits into the existing pipe or fitting and then the threaded plug screws into the adapter making the plug an access point for cleaning or pressure tests. In order to properly install this fitting, ABS cement is required to secure the fitting to the existing pipe and also to create a strong connection for other pipes and fittings in the system. Unlike PVC, ASB fittings and pipe do not need a "primer" in order to soften the pipe and create a solvent weld. This will save you time as you fix or construct your plumbing system. ABS pipes and fittings are used in a wide variety of DWV (Drain, Waste and Vent) applications. It can also be installed above or below ground due to its ability to be resistant to most acids, salts and alkalis.
