4 x 2 Inch ABS Flush Bushing, ABS Construction. This particular fitting is a Flush Bushing for ABS Pipe applications and has a solid ABS (Acrylonitrile Butadiene Styrene) construction. This fitting measures 4 inches on the one end by 2 inches on the other. A flush bushing is used in a piping system and will fit within a pipe in order to reduce the size going forward with the piping. In order to properly install this fitting, ABS cement is required to secure the bushing within the existing pipe and also to create a strong connection to a smaller diameter pipe. 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.
